Saltwater Stingrays
Hi
I have a 120gallon tank and I wanted to get a saltwater stingray. I would
also like to have a lionfish and some other fish is this possible. What
kind of stingray would you recommend for my situation.
thank you

Re: Weird behavior from an Emperor
Angel/General tank issues...
-08/27/08
Yes, I had slacked on my water changes when my RO/DI unit broke. I will
resume my normal regiment.
<And regimen, about face!>
Ok, so it's time to upgrade tanks. I have had my eye on a Ray of some type;
maybe the Cali Round one.
<Uhh, time to read... this is a cool/coldwater species...>
SO if I upgrade tanks, can I go with a 72X24X25 or do I have to go more with a
60x36x27.
The population I am envisioning would include my current blue/yellow tangs,
Emperor(If he makes it), and bird wrasse....
Thanks so much for your help!

Yellow spot skate 05/09/08
Good afternoon. I had a quick question that I wanted to ask you. I
recently noticed that an online vendor had a yellow-spotted skate in
stock. I have always been a fan of stingrays and skates, but I have
never had an adequate sized aquarium to house one. I am in the process
of setting up a 240g (4'x4'x2') tank, which might work for smaller
species of stingrays. I
emailed the company and asked for some information on the yellow-spotted
skate, but they were not able to provide me with much info. That
correspondence can be found below. Do you have any information on this
type of skate?
<I'm not exactly sure what skate this is. There are different skates
from different parts of the world that go by this same common name. Does
the company have any pictures of the animal?>
I am guessing that they eat crabs, snails, and shrimp. I was more
interested in how big they get and whether I could put one in a tank
with softies and LPS. Actually, an info you could provide on this
species would be greatly appreciated. The only thing I found that might
resemble this species is *Leucoraja wallacei, *but it doesn't look
similar.
<Leucoraja wallacei are not from South America, so it's probably not
this one.>
Thanks for your help.
<We should be able to help you more once we know what type of skate
these are. It's likely that you will have to design your tank to
accommodate this animal. Skates generally need a lot of open area (flat
bottoms, little rock). So you can keep at least that much in mind when
setting up this tank.>

Atlantis AquariumClearnose Skate, sel.
8/3/07
Hello WetWebMedia Crew!
<Hi>
I have a few questions concerning a species of skate called a "Clearnose
Skate".
Before I start, I must point out; I am completely unable to care for any
Batoid species at this point in time (freshwater or saltwater), and I will
not be until I graduate from college, which is a long time away. A website
called "Sharksupply.com" is offering the Clearnose Skate at 5" in size for a
mere $50, which sounds fantastic since that's the cheapest ray I've ever
heard of. Based on some sketchy research I found that this skate gets just a
little over 2 ft in length at most (correct me if I am wrong). Judging from
that this sounds like a great "first ray" species. I would just like to know
how big a tank would be required for one, maybe 2 individuals, as well as
preferred temperature and environment. Any guidelines would be appreciated.
Also, would this skate be compatible with other Batoid species like
Guitarfish? Or do skates prefer only hanging out with other skates? I've
always seen in public aquariums eagle rays, stingrays, and guitarfish all
hanging out together, but no skates. Is there a particular reason for this?
Finally, what is the general behavior of this skate? I'm not so sure if I
would care to drop a few grand to set up for a fish that does nothing but
sit buried in the mud all day. Does this species spend all of it's time
sitting around lazily, or is it at least mildly active and entertaining?
<I'd read here and linked files above for information on this.
http://www.wetwebmedia.com/rays.htm?
Thank you for your time.
<You're welcome. James (Salty Dog)>
Mmm... Porcupine Puffer fdg., Keeping a Batoid 2/18/07
Hello Gentlemen (and Ladies),
<Heeee! Oh, you're not joking... Okay>
I have 10 years as a paid aquarist and have volunteered at several public
aquariums across the country. I would like to think that I have a pretty
good amount of experience with marine fish and invertebrates, but I do have
a few quick questions that I was hoping you could answer for me.
<Will try>
I have a 3 inch porcupine puffer (Diodon holocanthus) in my large fish
only tank with live rock. I have had him for about 3 weeks and thus far I
have not been able to get him to accept frozen or freeze dried foods.
<Mmm, does happen... as you're likely aware... Puffers of all sorts,
sizes... go on feeding strikes often when moved... sometimes for no apparent
"reason">
I have fed him live feeder guppies once per week, and he has managed to
catch and eat a few. He is too slow to catch more than one or two per
feeding, and my Humu Humu trigger will no doubt eat any live Ghost shrimp or
clams that I offer before the puffer can make his move.
<The presence of this trigger may be a large part of the reason for not
feeding here...>
Any thoughts as to what I can do to get him to begin accepting thawed frozen
food or freeze dried krill/plankton?
<An open shellfish... and either removal of the Balistid, or moving the
puffer to better psychological setting>
My second question involves aquarium stingrays. I am setting up a
saltwater system for a friend, and he wants to keep a stingray. I have
informed him that they are by no means easy to keep, but he wants one
nonetheless. I am installing a deep, sugar-fine sand bed and minimal
rockwork, to maximize space. The tank is 240 gallons with a sizeable
footprint. There won't be any triggers or puffers in the tank, and the ray
would be the last animal added. Other than adding a few live crustaceans to
the sand bed to aid in feeding (and thereby acclimation) is there anything
else we can do to increase our chances of success?
<Mmm... be careful when picking out species, a specimen...>
We are looking at both the Blue Spotted Ray and the California Spotted
Ray.
<Both exceedingly poor choices historically... The California will/would
require a chiller... keeping only other cool-water species...>
Thank you for your time. I very much enjoyed reading my copy of "Reef
Invertebrates", and I love the work that you guys do.
Best regards,
Danny Riskam
<Do have your friend look over a copy of Scott Michael's "Aquarium Sharks
and Rays". Bob Fenner>
I have a California round and a blue dot sting ray in a 150 gallon
2/18/07
Hi I have a quick question I have a California round and a blue dot
sting ray in a 150 gallon.
<Mmm, one's tropical, the other sub-tropical... see WWM, Fishbase.org re
these species... incompatible>
They are on their way to a 300 gal. but when I started the tank I put live
rock bio Spira etc to get the good stuff going now I have pulled everything
out so they have plenty of room. (this was 5 months ago w/ nothing in the
tank they've been fine) Question is how does good bacteria get in there now?
<Mmm, with transference of water, substrate, filter media... even the air in
time>
Will they be ok in there w/o anything? Do they need anything else.?
Michelle
<Mmm... no way to tell, as you haven't related what "they have" presently...
Please skim over WWM re Batoids in captivity...

Urolophus halleri (Round Ray), not eating, not tropical 9/18/06
Hey Crew,
We got a Cali ray that came in to our store last week on Thursday. The ray
hasn't eaten yet. It seems like he doesn't want to eat. We have tried frozen
squid, krill, gulf shrimp, and live ghost shrimp. None of them have worked.
She swims all day and all night and rest for a little bit. Should the ray be
eating by now? I've looked at some of the articles on your site and nothing
helped. We have been hand feeding and stick feeding.
Thanks,
Ben
<... is this fish in "hot water?"... See here:
http://fishbase.sinica.edu.tw/Summary/speciesSummary.php?ID=2580&genusname=Urobatis&speciesname=halleri

Stingray mega system - 09/07/06
<Hey Dan you are in luck, I've kept some stingrays and have some
experiences to share with you.> After seeing all the great advice on your
site, I thought I might tap your brains as well with a few
questions on my mega large, stingray system. I have been in the saltwater
hobby for almost 10 years, currently running 3 other tanks, so I know the
basics, but this is my first go-round with stingrays. After
seeing something
at a LFS, I decided to build my own "lagoon". The display tank (not
counting the filter) is Approx. 1,200 gallons, in the lower level of my
house, with a pond liner. It is roughly 8 foot by 8 foot and 2.5 feet
deep. It is filled with a 1-2 inch
deep sand bed made of sugar sized Aragamax, and has a small (30-40 lbs.) pile
of live rock in the center. It is now time to stock the system. My
questions are these:
-Should I be worried about the pond liner (40 mil typical outdoor pond
liner) being punctured by the stingrays' spines/barbs when they swim
around? <Based on my experiences no. Stingrays aren't usually aggressive
unless they are provoked. Meaning they don't go around with their rays ready
to puncture all the time.>
-I would like to house a variety of stingrays in there, and after doing the
research it seems that, in a system this size, I would be able to put 3-5
rays in there total. Could I maybe do a Bluespot or two, maybe a California
round or two as well? I know Bluespots are difficult to keep, but due to
the size of my system, I think many of the problems most folks
encounter will be overcome. <My friend kept Bluespots without any troubles.
I believe that the major thing with them is that they need to be shipped in
healthy and from a reputable dealer. But I don't think you are going to be
able to keep Bluespots and California species together because Bluespots
need a warmer water tank than the California rays.>
-Finally, in a system this size, do you see any problem with adding a big
fish or two (like a grouper, something that will not generally pick at
rays)? <You possibly could add some fish but let me warn you RAYS ARE
HUNGRY and will eat and or attack lots and lots of other fish and devour
them pretty quickly. Especially, in my experience, the blue dots.>
Thanks in advance for the advice, and the past advice to others cautioning
them to treat these animals for what they are: living creatures who need to
be cared for, not merely a "thing" to be had. <If it was me I would plan on
trying to keep a pair of stingrays and I would put any other fish you
planned on keeping in first and letting them get establish. Let the system
stabilize and get settled as well. Realize that stingrays like other
predatory fish are going to produce a tremendous amount of waste and that
you'll need to plan your filtration to accommodate them. Realize that most
stingrays are going to be larger animals and that's going to require special
equipment for changing things in the tank. Realize that you aren't going to
want to reach your hand in the tank for many reasons. Figure out other
options for cleaning. Bless Steve Irwin's soul, but these animals do have
the potential to kill so keep that in mind as you choose what to do in this
system. Hope this helps and if you have any more questions just let me
know. Good luck, MacL>
Stingray laws - 09/03/06
Do you know in which states in the U.S. it is legal to own a stingray in
your home aquarium?
<Mmm, freshwater or marine? Only presently aware of the former (Potamotrygonids)
being restricted in our State of California>
Everyone else I ask just says "don't tell anyone you have one" but I don't want
to do that. I want to know. We just got an aquarium, 110 gallons.
<Too small for marine Batoids...>
We haven't put anything in it yet, the stand is still being built so we're
trying to weigh our options and we love stingrays. We are in the military so we
move every few years, even if it isn't legal in this state, it may be legal in
our next.
<Contact the State(s) "Fish & Game"... they will know. Bob Fenner>
Sale of Urobatis jamaicensis 8/8/06
Hello Bob, I saw the aquaria trade article you wrote on webmedia.com and was
wondering if you have an idea how to come across the number of stingrays,
particularly Urobatis jamaicensis that are sold annually, and for how much. (Any
info would be helpful) Please contact me with any suggestions you might
have to acquire this information. Thank you in advance.
Cheers, Dan Fahy
<Mmm, likely the best place to look is through a roster/listing of saltwater
collectors/dealers that are members of the FTFFA... Please see here:
http://www.ftffa.com/
There are likely quite a few fisherfolk who could supply this species out of the
TWA as well... Good fishing! Bob Fenner>

Sharks and rays ... incomp. - 05/20/2006
Good day folks.
<Noam>
I have read through hours of your postings and although the information is
invaluable I have not found the answers I seek.
<Good>
I am currently cycling a 250 gal tank. My goal is to house one bamboo shark, and
one ray. I know the California ray is the right size and temperament however it
requires colder water temps compared to the Shark.
<Yes>
Can you please suggest a Ray that is both small in size, and has the same water
requirements as the Bamboo shark.
Thanks from Chicago.
<There are tropical species... not often offered in the trade... and I don't
encourage mixing these groups... too much "dust", activity from the Ray... Bob

Urobatis jamaicensis in captivity 4/25/06
Hello my name is Riley I have read a lot of information on stingrays. I
currently have a P. reticulatus, but I'm also interested in marine rays I have
researched and found that Urobatis jamaicensis is the most suitable for life in
an aquarium. I searched your site and found no information regarding this
ray other than ("Urobatis jamaicensis (Cuvier 1816), the Yellow Stingray.
Western Atlantic; North Carolina to Venezuela. To thirty inches wide. Aquarium
and
Cozumel photos.") I would like to know the basics and the requirements of
this beautiful animal.
<Mmm... you should peruse the article, FAQs on Batoid fishes...>
Such as tank size,
<Hundreds to thousands of gallons... at least twice the width of the intended
maximum size, thrice the length. Height not very important functionally>>
eating habits etc. I would also like to know how to go about purchasing this
ray, what sites or sources carry it.
Also what are appropriate tanks mates? Your help is most appreciated.
Thank you for your time!

Sting Ray Care 10/4/05
Hi,
<Hello, Adam with you tonight.>
I Love stingrays and have had very good luck with California Rays (Urobatis
Halleri) <Very neat temperate species.> and extremely bad luck with a (Taeniura
lymna) Bluespot Ribbontail Ray throughout my aquatic career. <This is not
surprising at all. Often they die within the first week or two of captive life
and rarely accept food. Even when they occasionally accept food they seem to go
on hunger strikes at times and often never resume feeding. Very rare that this
animal is kept successfully long term. This one is best left in the ocean.> I
have been lucky enough to obtain a baby Bali Bluespotted Stingray (Dasyatis
Kuhlii) which is currently residing in my 50 gallon quarantine tank. <Ahh yes
this “look alike” species is much hardier. Generally they are easily coaxed into
taking frozen fare such as fresh market fish, squid, krill, any meats of a
marine origin really. You should have a fine layer of sand on the bottom of the
tank, at least 3” in which t can bury itself when threatened. Coarse sand will
cause irritation to its smooth skin, which can lead to bacterial infections and
even death. You’ll also (eventually) need a tank of at least 300 gallons with
lots of surface area and minimal rockwork. Keep in mind that as with all
elasmobranchs this species is sensitive to stray electrical voltages, heavy
metals, and high nitrate levels.> I have tried to search both WetWebMedia and
the web and have not found much information on care about this stingray. Please
help me learn to provide the best possible atmosphere for this animal.
<I also will take this opportunity to plug Scott Michael’s book “Aquarium Sharks
and Rays.” It is filled with tons of good general information. However I will
say that I disagree with many of the listed tank sizes for some species. I
believe all sharks and rays should be treated to X-large spacious tanks (not
closets) or left in the ocean.>

My newest addition! Misplaced skate 7/14/05
I acquired my first stingray
<Uhh, mistake number one... this is a skate... family Rajidae>
Saturday, July 9th; I have attached a picture of my "Stinger" (my two
year
old daughter named him). He is doing wonderfully! I have done a ton
of
research online but it is very limited. I have purchased a few books
but
have yet to receive them.
<Mistake two... too late>
I was wondering if I might ask you a few questions?
1. I bought him at Big Al's Aquarium Superstore, it was described as
a
salt water ray converted to fresh water (my guess is because I am in
Florida
and fresh water rays are illegal to own, sell, keep, breed, etc.). Am I
to
treat and feed him like a true fresh water ray?
<... is not a freshwater species... will be dead soon if kept in such...
Mistake three>
2. I kept the diet that the store had him on-frozen silversides,
krill
and bloodworms. According to some articles I have found he is
considered
undernourished (you can see the "dent" between the eyes). I started
with
one block of food twice a day but he still seems hungry so yesterday he
got
four blocks. Am I in danger of over feeding!
<Nope>
3. Is it a male? I see what I consider "claspers" at the stinger
base.
<Me too... I don't have claspers, but I see these also on the photo>
4. In 900 gallons I keep four koi (2 small/2 med size); four large
comets
(one is in the picture); 6-8 feeder goldfish; and Stinger-is there room
for
another ray?
<... no>
I would appreciate ANY advice you can send my way, I am so fascinated
with
him and it has only been a few days!
<What can I say, write? This fish is doomed... of the two hundred or so
species of skates, none are strictly freshwater. Enjoy this animal...
while
you can. Bob Fenner>
Thank you,

Sorry to say I was duped! Revisiting the "FW" ray... 8/24/05
I bought a "saltwater turned freshwater stingray" at a local fish superstore
a few months ago. I learned the hard way that it was actually a Skate.
Anyway I have him in a koi and comet pond (about 900 gallons) and he has been
doing excellent until this morning. When feeding time nears he porpoises out of
the water with excitement. He will eat four silversides and three small shrimp
(twice a day). Two days ago we introduced squid. Since then his appetite has
dwindled. This morning he had no interest in food at all and was skimming the
top of the water and not the bottom. I did a small emergency water change and
added some aquarium salt (probably not enough to have mattered). His color is
more red than normal and I am scared I will lose him.
Any suggestions, PLEASE!!!!!

seawater to have the barest chance of surviving... Bob Fenner>
Re: Sorry to say I was duped! Let the buyer beware 8/24/05

Ray on the dailies - Dasyatis sabina? 8/25/05
Hey, Bob!
Got a question for yah....
On the dailies I saw the fellah with the "ray"/skate,
and the link to his prior email which included an
image of the animal.
Is it possible that this is Dasyatis sabina, the
"Atlantic stingray"?
<No hon... Look at the rostral area... this is a rajid, a skate>
I have read some articles about
this species being found in purely freshwater
conditions, reproducing and living out their entire
lives.... I certainly don't know if this is true, or
even remotely accurate. Here's one of the articles
I've read, which includes an image that very closely
resembles our querier's animal:
http://www.ecofloridamag.com/archived/stingrays.htm .
Somewhere along my travels across the web, I have also
read that the animals collected and sold as
"freshwater" in the hobby are almost always collected
in brackish or marine conditions, and few survive long
at all. There goes my dream of legal freshwater rays
in CA. Sigh. Thoughts?
-Sabrina
<Few and dismal. BobF>
Re: Ray on the dailies - Dasyatis sabina? 8/26/05
Is it possible that this is Dasyatis sabina, the
"Atlantic stingray"?
<No hon... Look at the rostral area... this is a
rajid, a skate>
To be quite honest, I have absolutely no clue what, of
the rostral area, can be seen to differentiate a skate
from a ray....
<Ahh, sorry re... the "nose" or region just ahead of the eyes let's say...
is elongated, flattened... like a... skate! in Skates, family Rajidae...
Also the thorny dorsal spines are indicative of the family... distinguish it
from the many Ray families of Batoids>
My apologies, in any case. This whole
mess (and so very many others that we see every day in
WWM questions) certainly drives home the need for
emphasizing one's responsibility to research PRIOR to
purchase - I'd like to put something about this in the
book, perhaps as a section of its own, under
Introducing Fish.... or in the section on
compatibility.... or maybe preceding the fish
profiles. What do you think?
<An excellent (consistent) idea, plan>
In any case, I think
I'll type something up tonight, if not for the book,
then for posting on WWM, perhaps. Shall I send it
your way for editing/adding-on, if you wish?
Thanks,
-Sabrina
<If you'd like... I am accumulating our notes, articles... on folders on my
active desktops... BobF>
I recently sent you a question about stingrays.
Since writing I have done some more web based research and have found that they are not a species suitable for aquariums. I suppose you just take for granted that if a fish is on sale in a shop it is suitable for an aquarium.
Unfortunately that is not the case.
<You are right on all accounts>
I totally agree with your stand point and they should not be imported.
<Ah, good to have company>
I would urge people not to support the importation of these fish.
<Good>
I have had mine for quite a while and everything was great. I think it is probably too late for the female now, but as the male is active, alert, eating and importantly growing I hope he is going to be okay.
<Me too>
He is in a 150 (imperial) gallon tank with sand, rock work and a cleaner shrimp. He seems okay. Fingers crossed...............
<Mine as well. Be chatting my friend. Bob Fenner>

Ray recommendation?
Bob,
I'd like to get a small ray, but I've seen how much trouble many of the
species can be, especially when they're inappropriately caught from the
wild. What would you recommend for a beginner? (To rays, not to keeping
fish in general.)
<Please read here: http://www.wetwebmedia.com/rays.htm and the cartilaginous fishes articles and FAQs files linked beyond>
I'd like something small (for a ray), that's not likely
to die on me in a month or two. I will be buying a new aquarium specially
for it, so I'd also appreciate advice on an appropriate corresponding size.
(At this point I'm in the research stage, and I'm going to get a copy of
Scott Michael's new aquarium shark and ray book, now that it's available.)
<Yes... very worthwhile. Bob Fenner>
Thanks much,
Jen
Please reply soon!! (stingrays in IL)
I recently emailed you and thought of a new question. Do you know if
stingrays are legal in IL if not do you know of a sight where I can find out?
Thanks again,
Timothy
<Marine Stingrays are not dis-allowed in any U.S. state that I'm aware.
Freshwater ones are illegal in some (like California). Please direct your query
to the State's Fish and Game agency. These can be found by searching in the
Yellow Pages... or on-line via State listings/directories. Bob Fenner>
Blue spotted ray (larger questions of knowledge, morality)
Why would the store sell something that would die??
<Perhaps they're ignorant of the species historically low aquarium survival. Maybe to "make money"...>
don't you think you're pushing the dying fact a little to far.
<Mmm, no. Put yourself in my/our place/s. Having been in the trade for decades, seen, had many of this (and other notorious species) die so easily, it seems only realistic to warn others of their "chances"... perhaps spare a few specimens untimely loss. What would you do?
Perhaps a romp through the various marine hobbyist listservs, asking for input of how others have fared would convince you?

- Captive Electric Rays -
Dear WetWebCrew,
<Greetings, JasonC here...>
Hate to be such a bother, but you guys are by far the best source of information
I have come across. Just think of me as your unskilled apprentice, always
curious. My friend just bought an electric ray to put in his 300 gallon tank.
<Ohh nooo... please tell me you are joking.> He's had it set up for quite
a while and is running adequate filtration and the water quality is fine and
stable. We tried to ask the guy at the pet store some questions, but he didn't
seem to really now anything. First off, is there any supplements he should use
to better prepare the ray for aquarium life? <None... please consider trying
to get this ray back in the sea.> We've already used "Cycle" to
help ease the transition. <Cycle isn't made for such things.> I've heard
iodine is good, or any other essential vitamins/nutrients? Second, what should
be done properly regulate its sleep cycle? Right now, the lights are coming on
at 10 am, and are going off at 11pm. <Should be fine.> It was my
understanding that rays and sharks are nocturnal so we don't want to mess up
anything having to do with his natural rhythms. <Not always, but often their
food is nocturnal so...> Also, we tried feeding it both live ghost shrimp and
skewered squid, neither of which it was interested in. Is this just because its
still getting used to its new home? <It could also be because most all
electric rays are not tropical fish and need to be in a chilled tank.> How
often should he be fed, I've read twice a week, no more, no less. What is the
best method of feeding it? Any other important info you could add would be
greatly appreciated,
Sincerely,
Bob Benson--
<Bob, there just aren't enough ways for me to voice my disappointment. These
rays are absolutely inappropriate for anything but the largest public aquariums,
and for your friend to have purchased and placed it without knowing the care
requirements in advance has likely sealed its fate. Please start by picking up a
copy of Scott Michael's book, Aquarium Sharks and Rays - detailed care
requirements are contained within. But let me quickly quote his book from the
section Captive Care: "Unfortunately, due to their selective food habits,
electric rays do not fare well in captivity. They feed primarily on annelid
worms, both in the wild and in captivity, so unless you have access to a ready
supply of these invertebrates, your chances of keeping an electric ray alive are
slim." Sorry to be the bearer of bad news. Consider poking your friend to
do the research FIRST.
Sincerely, J -- >
California Stingray
Bob, My local pet shop has a California stingray [Urobatis halleri] Do they
get to be two feet in diameter? Also what temp. is it for a cool water species?
Thanks Tom Reeder
<About this size yes... and yes to this being a cool/coldwater organism.

What species of stingray will live in a 75g tank?
None in my opinion... please read here
http://www.wetwebmedia.com/FWSubWebIndex/fwstingrays.htm
The smallest "common" species in the trade is 14" as an adult.
Your tank is only 18" wide. Please consider other fishes altogether. There
are many unique and wonderful choices. Start browsing some of these wonderful
possibilities starting here:

Some dasyatids... in Puerto Rico
Robert,
I am a graduate student in Puerto Rico in Fisheries Biology and I found your
site while searching for species information on freshwater stingrays. The reason
I am writing to you is because you made a statement on your website "None
are currently utilized in the aquarium interest as far as I'm aware" and I
wanted to let you know that I have just recently seen Dasyatidae in an aquarium
for sale in a local mall.
<Mmm, there are a few dasyatids that are freshwater and brackish... and a few
of the Amazonian freshwater rays (family Potamotrygonidae) are used in the
hobby>
Now, I was perplexed by this because I do not know of this species being in
freshwaters here in Puerto Rico. I just thought I would let you know that they
are in fact now being sold in the aquaria market.
Cheers,
Kimberly
<Thank you for this. You may be able to identify this to species using
fishbase.org (with the country search). Bob Fenner>
Good vs. Bad Blue-dot Stingray Species- what's the diff?
Dear Bob,
<Anthony Calfo in his stead, my friend>
We've been wondering about blue spotted stingrays and were wondering if they are
reef compatible
<not really. Even if your definition of reef-safe excludes their crustacean
(shrimp/crab) diet... you still have to contend with their need for large
spacious sand flats. A rockscape is a recipe for disaster with skates and rays
(causing abrasions and perhaps leading to their demise) in the confines of
captivity>
and also what size tank you would recommend for keeping one.
<200 gallons bare minimum... and more importantly, the most common species in
the trade- Taeniura lymna, is staggeringly difficult to even keep alive (truly
for experts and public aquaria only). If you must have a blue spotted ray,
please seek the hardier Dasyatis kuhlii... less blue spots but much more likely
to survive (small and adaptable). Scott Michael's "Sharks and Rays" is
a must have book for you before you proceed too, mate>
Look forward to hearing from you soon. Many thanks in advance,
Martin & Lynsey
<with kind regards, Anthony>
Wanted: sting ray
to who may concern i recently have a 150 gallon salt water fish tank. I have
a banded cat shark maybe about a foot long
i am thinking about buying a blue spot sting ray i would like to know if it is
possible to add this sting ray.? i not only have my banded cat shark i also have
1 lunar wrasse,1yellow tang,2 niger trigger, 1 green wolf eel,1snow flake eel,
and 2 maroon clown fish <This would not work as this tank is too
crowded and Bluespot are very challenging to get to live for long. Cody>
How to buy rays?
I have been intensely searching the internet for rays to buy. Who
should I contact? Eager for a Ray, Dawn Bailey

You can call him Ray, he's new and not tropical, but hungry
Hi:
I just got a California ray yesterday. It's quite small
(the disk size is about 3 inches). The fish looks fine and has been stay at the
sand bed. However, it does not move much unless my cleaner wrasse is bothering
him. I am wondering how should I feed it?
I tried swing a piece of squid/shrimp in front of it, buried the meat underneath
the sand near him. He just wouldn't eat. I think later I will get a turkey
baster to shoot some brine shrimp in front of him to see if that works. Please
give me some suggestion, thanks!
regards,
Howard
<Some suggestion? Likely to return the Ray whence you got it. Do you have a
chiller on this system? This is not a tropical fish... it might not be eating
simply because it is too warm. A cleaner wrasse? Please take the time to read
through (use the marine index or the Google search tool at the bottom of the
homepage) of our root web: http://www.wetwebmedia.com/

A Ray Of Hope?
Hi,
<Hi there. Scott F. here with you today>
I have just acquired a Taeniura lymna. He is about 6-7" and was
at the LFS for only 4 days before bringing him here. I
place him in a 7" (220 gal) with mostly angels as tankmates.
<Yikes! Please be sure to quarantine all new arrivals for a minimum of three
weeks before placing them in the display tank...Better for everyone...>
I have looked everywhere and cannot find much info on these guys. Even
on your site, there really isn't much. I've also heard that Bob has
one of these beautiful creature's??
<I don't believe that he does have one...It's one of the worst of a pretty
bad family of fishes to keep in captive systems. I don't like to sound negative,
but I think that, despite your good intentions, you purchased a fish that really
should not be kept in captivity. These fishes almost always starve to death for
lack of available food sources in captive situations. They need a huge sand bed
area, filled with infaunal life. If you can get this fish to eat prepared foods
(like Mysis, frozen Cyclop-Eeze, or the like would be among the better choices),
it will still have a very difficult time adapting to captive life...Sure, you
might have the one in a million that does, but I'm afraid the odds are not in
your favor.>
Do you know what he feeds his? how he feeds it, temp he keeps it at etc. Also,
my French is a little nippy with it...is this a big problem?? Can the ray defend
himself? Or is this too stressful?
<Well, the added challenge of a nippy tankmate is really reinforcing the odds
of failure, I'm afraid. At best, he fish may hang in for a while, but if you are
going to have any chance at all, I'd recommend a tank of his own...>
Thank you so much I for one have really truly appreciated all the
help I've received from you guys. My French would not be alive today
if it weren't for you!! Hopefully now you can help me with Raymond!
Thanks again, Lynn
<Well, Lynn- I'm afraid that we cannot be of too much help here. Regretfully,
retailers continue to stock these beautiful, but non-viable (for aquarium use)
animals. The best thing that we can do for them is to vote with our wallets, and
not buy them. Once there is no market for such animals, there will be no reason
to import them. I know that you meant well, and I encourage you to do your best
with this animal, but please read up and know the odds ahead of time when you
decide to purchase ANY animal, especially one with such a difficult reputation.
Do your best...Good luck! Regards, Scott F.>
A Ray Of Hope? (Pt. 2)
Thank you, just wanted to let you know that I returned the ray
the next day. He was looking stressed to me, and what little info I
found... encouraged me to return him. After getting your opinion I am
glad I did so. I'll not make this mistake again.
Thanks again
Lynn
<Well, Lynn- I'm glad that you were able to get him back to the dealer. I can
only hope that they can find this fish a more suitable home (perhaps a public
aquarium?). Despite this unfortunate experience, I think that your compassion
and enthusiasm will serve you well in the future...Don't be discouraged...Keep
learning and growing in the hobby, and share with others! Good luck! Regards,
Scott F>
California rays in a commercial aquarium environment
I am currently looking at buying a commercial aquarium/museum here on the
Pacific Northwest (U.S.) coast. The owners previously had two seals - full
grown- in a very large "pool" - the dimensions would be close to 20ft
long - 8 ft wide made of concrete.
<A small/dismal world for Phocaena or Zalophus...>
I am not considering reintroducing seals but filling the tank with gravel and
then sand (the proper sand per your web info I have read) and putting in a few
pacific water rays in there. Something that the visitors could interact with
(pet and possibly feed). The water is pumped directly from the ocean, into a
sand filter and then into the 19 tanks and the seal tank and then pumped back
into the ocean - so the temperature of the water is that of the local waters. My
questions would be as follows: What type of ray is it that one of your writers
had said was a very social ray?
<... maybe Myliobatis... all rays in this application take some acclimation
to these circumstances...>
Also, if we didn't debarb them and just let them be on display (no
petting/feeding) would it be ok to put them into the ocean in the winter if we
shut the aquarium
down- and then repurchase some in the spring?
<Should be, yes>
Or are they hardy enough that we might be able to work out a "loaner"
program with one of the big aquariums on the west coast (Long Beach/Monterey/Sea World)
and ship them??
<You could ask, look into this, but I strongly suspect that the respective
costs of shipping the animals, versus buying locally (likely through fishers)
will be prohibitive>
Any input, even if the question wasn't asked, would be helpful. This business
venture is more of a career change and I would like to be informed as much as
possible if this could be an attraction vs. me thinking it could be.
Thank you in advance... and thank you for all the info on wetwebmedia. It has
been very helpful.

<I am cc'ing a cohort, Paul Mansur here, who volunteers at the Monterey Bay
Aquarium in the hope that he will in turn send your note on to Dave Cripe,
others... for input. Bob Fenner>
Stingray (Dasyatis kuhlii)
Hi,
I was wondering what ray besides the blue spotted stingray would live happily in
a 240 gal for it's entire life (no tankmates)? Also, I cannot find any websites
that sell the Dasyatis kuhlii, they only sell the Taeniura lymna. Do you know of
any reputable sellers? Thanks!
-Alex
<I know the companies Dr.s Foster & Smith and Marine Center (.coms) to be honest
and competent. I would contact them re what rays they advise, can get. Bob
Fenner>
Urolophus halleri?
Hey guys, I was wondering if Urolophus halleri was a cool water or tropical
species? LiveAquaria.com has it as a tropical (72 - 78) but I've heard that it's
a cool water also.
<It's found from Northern CA, where temps are around 50-55, all the way down to
Panama. Keep in mind though that most individuals in the trade are likely
coming from warm waters and may need to be acclimated slowly.>

Keeping Rays 6/6/05
I have a few questions on bat rays. Today I went to my local aquarium and fed
the bat rays. I really liked how they suck on your fingers. I wanted to set up
a saltwater "Pond" in my basement. I was wondering how I could get one and how
much it would cost. (a really small one)
<Here is info on building a pond: http://www.wetwebmedia.com/ca/cav1i1/pondDIYCalfo/diy-pond.htm. See
here for some basic ray husbandry and species selection tips: http://www.wetwebmedia.com/marine/fishes/index.htm>
and I also wanted to know if it is legal to catch your own and keep it. If you
can please email me back with my questions answered that would be great. David
Moore <Generally, it is legal to collect livestock that is also legal to catch
for food or sport as long as you have a fishing license. Do check with the fish
and wildlife department wherever you plan to collect! Best Regards. AdamC.>
