A Few Common Shrimps for the Marine Aquarium by James W.
Fatherree, Shrimp Gobies,
Hi crew, I currently have a large (6") pink spotted watchman goby in a 6 foot
150 gallon aquarium. His territory takes up the left 3rd of the tank, he never
ventures to the other side.
A friend is selling a 3" 'blue spot' watchman goby (which I believe is just a
different colour variation of a yellow watchman goby?) with a red banded pistol
<Might be the Cryptocentrus cinctus. See my pix here:
I am curious what you believe the likely outcome would be if I added this goby
and shrimp to my setup.
<Likely will get along, possibly pair up!>
A. The two gobies would pair and/or share a cave. B. The new goby would setup
territory on the right hand side of the tank and both gobies would ignore each
other or C. The existing goby will harass or kill the new goby.
I have read a lot on pairing watchman gobies and I believe they would pair if
they were both pink spots or both yellow but really haven't been able to find
any info on two different watchmans pairing.
Thank you for your assistance on helping me make my decision :)
<Were this my system, set up, I'd try putting all together. Bob Fenner>
Re: Pairing gobies 2/19/19
Thanks so much Bob, you give me confidence :). I will give it a go and let you
know the result.
<Thank you Nicole! BobF>
Re: Pairing gobies 3/21/19
Hi Bob, it's been a few weeks since adding my ywg and pistol shrimp and I said I
would give you an update.
While the two gobies did not pair up there has been 0 issues housing them
together. Honestly I am not even sure they know the other exists lol.
<These "meeting up" affairs often take time; just "happen" all at once at times.
Thank you for giving me the confidence to try it!
<Thank you for your report Nic. Cheers, BobF>
Re: Pairing gobies 3/21/19
That would be great if they paired eventually but all I really cared about was
that they could coexist, so I am happy either way!
<What would our late mum state? (Just) Wait and watch... B>
Wrong id: Shrimp Goby POTD; and Alpheid comp. q.
Was browsing WWM for some answers.
The first photograph tagged "Amblyeleotris latifasciata, the Red-banded
Shrimp-Goby. Western central Pacific in distribution. To a little over
three and a half inches in length. Occasionally imported as an aquarium
species. Bali 2014" shows an Amblyeleotris diagonalis pair with a single
Alpheus bellulus. No A. latifasciata in there.
<Ah, thank you for this correction>
Now to jump to the my pain:
I have formed the forth Amblyeleotris latifasciata pair and managed to
form a Alpheus bellulus to go on the same team.
They've went through a six weeks quarantine with an Alpheus bellulus
shrimp, then moved in my RSM130.
All was well for a week. This video is from yesterday
https://www.youtube.com/watch?v=ooPVVypqxXY and as you can see they were
a happy quartet.
This morning, one of the shrimps was displaying erratic behavior
(leaving the nest type), going around the edges and swimming into the
open, ignoring any goby protection offer. An hour later, he was fully
fitted inside one's goby mouth. The other goby was picking pieces, so
finally the shrimp was successfully swallowed.
Now it's job as always, with a pair of Amblyeleotris latifasciata and
only one pistol shrimp.
<Mmm; I'd stick with this arrangement, having just the one Alpheid>
The tank is a RSM130, is six months and two weeks old, livestock is -
pair Amblyeleotris latifasciata with (now) one Alpheus bellulus, 1x
Ecsenius stigmatura, 1x Ecsenius pictus, 1x Lysmata amboinensis, 4-5x
Paguristes cadenati, 2x Cypraea tigris, 5x Monetaria annulus, 6x Turbo
fluctuosa, 20+ Nassarius vibex (20 adults and now countless babies), 3x
Nerite sp, some Stomatella.
Last water parameters (from yesterday):
- temp 27.5°C (termometru JBL)
- pH >8.0 <8.3 (Salifert)
- Alk 9.3 dKH / 3.30 mEq/L (Salifert)
- NO3 25 mg/L (Salifert)
- Ca 380-390 mg/L (Salifert)
- Mg 1200-1230 mg/L (Salifert)
- SG 1024.6 (Hidrometru Tropic Marin)
- PO4 - no clue, I run some Rowaphos in a sock though and have no algae
growth on the glass anymore
The tank journal link is
http://www.acvariu.ro/forum/posts/list/80/36966.page , unfortunately the
forum is in Romanian, also littered with NSFW photos (my forum members
appreciate everything natural and beautiful, not restricted to fish) -
I do not know what to make out of this, but my previous pair of A.
latifasciata consumed both their shrimps at the same time within a week
of being moved in the same RSM130 tank from a smaller tank where they've
lived peacefully for a lengthy (+ two years) amount of time (see here
https://www.youtube.com/watch?v=CNJ1z6DDuk8 ). Needless to say, I've
lost that pair sometime after the incident (upon return from a ten day
holiday in January 2017, the girl stopped thriving, became emaciated and
wasted away, the male followed a week later - stopped eating upon the
death of his partner). Video prior to introduction
https://www.youtube.com/watch?v=G8gSh6hCBIQ with very excited gobies
and soon after introduction in the tank
My theory around these killings is that the Amblyeleotris latifasciata
as a species is developing more marked attachments then other
Amblyeleotris species and upon being left they become jealous. I feel
these fishes suffer when I'm not taking some time near the tank as they
are always attention seekers and this goes beyond begging for food (if I
just throw the food and neglect them they keep flashing). Also, they
cannot stand being left by their shrimps as it sometimes happens and
upon no other alternative, proceed on consuming them. I must also
mention that they do not hide when I introduce my hand in the tank and
that all the transfers (from the LFS bag to tank and from tank to tank)
have been made by hand.
Please feel free to import and use the photos and videos from my YouTube
channel and from my tank journal at your own will.
<I'd offer a bit more meaty food/s more frequently... pipetted directly
to their area; and hope for the best here. Bob Fenner>
Re: Wrong id 5/27/17
Thank you for the quick answer.
I'm aware there is no clear cut answer, just wanted to leave a trace of
this unusual behavior.
I'm currently feeding them (and my other four nano tanks) a mixture of
frozen food (Gamma Marine Quintet: Mysis, brine shrimp, krill, seaweed,
razor clam) at each meal with some occasional dry food snacks to calm
down the begging. They are not slim by any standards.
I'll come back if there is any progress or progression on this.

Alpheus Shrimp- Pistol Shrimp Compatibility
Dear Bob & Crew,
Thanks again for your on going passion for aquatics! Still waiting for a follow
up to "Reef Invertebrates"!
<Ahh! I would tell you that I've been working on; and am almost (within a few
hundred hours) of finishing the two Reef Fishes books/volumes; and am
serializing the "Corals" tome via the UK magazine UltraMarine>
I had a brief question today. I had a Alpheus bellulus tiger pistol shrimp in my
155g reef tank but discovered that it was killing most of my snail population.
<Yes; common... can/will kill hermits, other small crustaceans as well as small
It was a rather large pistol, going on 3", with mostly gray stripes- not much
coloration. It has long since been removed. I have seen many smaller, more
colorful pistols (not sure if they are the same genus) and was wondering if they
would be more compatible with snails.
Thanks so much!!Joe
<Not as far as I'm aware. The predatory behavior is very likely a function of
size (as you state); as well as hunger and opportunity. IF trying another, I'd
start it small and keep it well fed (as in with a feeding stick). Bob Fenner>
Cryptocentrus feeding/ compatibility conundrum
Much gratitude from myself and my fish...Firstly, I have a little something to
share. I have a yellow watchman goby and Randall's pistol pair living happily
under a mushroom rock in my 55. They both eat well and I would say that little
yellow guy guards his shrimp at least as well as my dog guards my home. So I
believe I have mostly read...and read, and read....that YWGs are carnivores.
Some have called them omnivores leaning towards carnivores.
So I feed NLS pellets, NLS flakes, others, frozen: emerald entree, mysis,
Cyclops....sometimes fortified with Vita Chem. I have other foods, but those are
the staples. The YWG eats whatever floats past his little cave, never venturing
more than 5 inches from the entrance. I have almost fully recovered from a bout
of green hair algae, (compulsive over feeder in recovery) with the exception of
the back glass. This is mostly because I haven't cleaned it off in 6 months or
more, not out of laziness, but an outdated concept of leaving the back glass
<Which I'm still a fan of!>
Today I decided to gradually clean it off, slowly, over time, as not to pollute
my water with 3" strands of green hair. I thought I had all my pumps off....I
didn't ..took a swipe with a sponge..and much of the algae went swirling around
my tank. Thankfully, it wasn't a whole lot. But oddly, at least to me, my YWG
went crazy. He started darting out of his cave, gobbling up every piece he
could, even the largest ones. And he just ate a half hour ago. I have never seen
him so excited over any food. I have never seen him pick at algae on rocks or
algae anywhere. I guess, at least in my tank, a YWG will eat green hair algae,
so long as I offer free delivery.......
Now my question. In my 55 gallon, I have the YWG/ Randall's pistol shrimp pair,
a bicolor blenny, and a royal gramma. Inverts....two peppermint shrimp, about 10
dwarf hermits, two jumbo Nassarius (travel together...cute!), about 6 Nerite
snails, one green mushroom and two small Palythoa colonies. No signs of chemical
warfare, but I'm watching.....
In my 30 gallon, I have a tail spot blenny and a black Ray (yellow rose ) goby.
Inverts.....5 dwarf hermits, 5 Nerites, 4 small Nassarius, and two small
Both tanks are peaceful and I don't NEED to add any more fish to either one.
See....I ought to just stay out of the LFS because now they have a cute little
aurora (pink bar) goby and in the very same tank, a YWG.....black and white kind
(juvenile) with a tiger pistol shrimp. I've watched this tank several times, and
neither goby seems to mind the other but I know what I've read about YWG...they
don't tolerate other shrimp gobies.
I assume this tolerance is due to the YWG being a juvenile as both gobies have
been in this tank for two weeks together. I can find little info on the aurora
goby as to whether or not he will tolerate other shrimp gobies.
<About as readily as any other of the same genus... which is to say; not
I did find a photo online of a black Ray, yasha, and aurora sharing a borough.
So my question is this.....do you think it possible that either one of my tanks
could accommodate the aurora and a tiger pistol shrimp?
<It is possible.... I'd have a floating/plastic colander ready to
isolate/separate the resident goby if WWIII breaks out>
The YWG in the 55 is stationed all the way to the left of the tank. I have a
"two separate piles of live rock" style aqua scape. One pile is on the right,
the other is on the left. Could the pink bar possibly live on the right, given
careful, purposeful placement and ample live rock?
<Yes; could possibly>
The LFS has another tiger pistol, goby less, in another tank. Would the shrimp
possibly help to keep him on the other side of the tank?
<Again; a gamble... I'd be sinking at least two, three small lengths of PVC
tubing with the end above the gravel>
OR..in the 30 gallon....would the black Ray, which I have read will sometimes
share his borough with other gobies, possibly welcome the aurora and pistol into
<This is more unlikely; a smaller possibility>
If I put them in together, might the black Ray think the aurora just part of the
price of gaining a pistol shrimp?
<Even smaller potential>
I ask because I can't find any info on whether or not auroras will tolerate
other shrimp gobies...aside from the aforementioned photo. Am I just asking for
trouble either way? Thanks so much! Alyson R.
<There is margin for good/bad to happen with these additions... better done
using screw cap plastic containers w/ holes in them (drilled is better vs.
melted; ask your dealer/LFS if they have some to lend.... to keep all the new
parties separated, but in view, smell of the established, for a few days. Bob
Experiences with Cryptocentrus cinctus and Alpheus bellulus
Just adding data points to the success/failure rate of goby and shrimp
pairing. In my case it was clear that the right species were involved, I
wonder if some of the failures are due to species mismatch.
<Undoubtedly your statement is correct. I'd throw in
"mis-introductions"; the use of too small a system, insufficient
habitat, mis-matched sizes even>
I have a goby shrimp nano running for four years now. The first pairing
was done when I set it up (after leaving it be for two months in order
to stabilize) and I had no issues. Although both Toby and shrimp came
from the same store, I didn't add them at the same time. There was no
trouble and the pair got along perfectly.
A couple of months ago the goby passed away and the Alpheus was alone in
the tank. I immediately noticed that it was much harder to see it,
except of course when I added food to the tank.
And this last Friday, visiting my usual LFS, I noticed something that
immediately put me in "rescue" mode. A ragged, thin and small
Cryptocentrus cinctus was swimming around an hexagonal tank, close to
the surface, in circles. The tank had some small Perculas and several
blue damsels, although I didn't witness any aggression. Anyway I was
planning to bring a new flat mate for the shrimp, so I purchased it.
After acclimation I released the goby into the tank. The behavior was so
different, which can only stress how critical is to provide the right
After the stress of being netted twice, transported in a bag, etc, the
fish got much calmer immediately upon being released on a sand bed. No
quick gasping, no frantic movements, just resting.
In a minute or so it turned around, had a look at the tank, noticed one
of the burrows made by the shrimp and it got inside. No trouble, no
clicks, nothing. And in 10 minutes I could get a quick shot of this
The Alpheus is visible again, the fish keeps really calm, and it gorges
with my generous feelings of krill Pacifica, mysis and Masstick.
So much for aberrant "phone booth" and similar tanks featured in
disgusting TV shows, pretending that some kind of magical, professional
skill will prevent fish stress.
<Uggh.... both Tanked and the Kings/FLA artificial coral shows are such
poor over-dramatic representations>
I must admit I was worried because the goby is smaller than the shrimp
(it's a young one) and it's rather thin, and I read that thin gobies
perceived as "too weak" could sometimes be attacked by the shrimp. But
so far so good, the only "violence" I've witnessed was a lot of pushing
when the shrimp was trying to release a lot of sand held between its
pincers and the goby was standing in the middle of the way, actually
<Thank you for this report; sharing. Bob Fenner>
Red pistol shrimp... comp. match for a
I was wondering if this pistol shrimp will be ok with my yasha goby....
I was told that this would be ok at the lfs. Thank you
Below is a sample pic of the exact shrimp. He is about 2 inches.
<Mmm; I do think this will work... I would introduce them slowly... in
an uncrowded setting of at least a few tens of gallons... with pieces of
small diameter (1/2" likely) plastic pipe dipped into the substrate for
both to find, hide in. Bob Fenner>
Adding another pistol shrimp?
Hello and thanks for your wonderful service--really appreciated. I
have a 29 gallon nano
with one pajama cardinal fish and one yellow watchman
goby/tiger snapping shrimp pair (as well
as some mushroom coral, macro algae, blue legged
hermit crabs and snails) which has been up and running
for a year and a half. I love the goby/shrimp pair--they've settled in
at the front of the tank where I can sit and watch
them. I realize that adding another watchman goby
and hoping to have them pair off is a futile
hope--but wondered about adding another pistol shrimp?
<Mmm; if you don't mind possibly losing livestock... trying to
get another Alpheid of the same species... might work>
From what I've read,
usually (in nature) there are whole colonies living together,
<Mmm; no... either single or pairs of both shrimps and gobies... never
more as far as I've ever encountered>
but I realize that aquaria live changes
behavior--so wondered what you thought or knew.
Very much appreciate your answers and your wonderful website.
<Cheers, Bob Fenner>
Re: Adding another pistol shrimp?
Thank you Mr. Fenner-thrilled that you replied-but not clear on the
<Ahh; clarity is pleasurable... let's begin again. The choice of trying
another Pistol shrimp that will get along w/ your present symbiotic pair
in such a small volume (29 gal. shape, size) is problematic. I give you
some odds, though not good, that adding another that might get along
So far, they've been very peaceful--no losses in livestock, as I've been
very careful with stocking and with targeted feeding. Read
an article about them (
) and got excited about the possibilities, but recognize that actually
re-creating the relationships in the tiny aquarium I now
have would be difficult. Really appreciate your web
page--and your book. The extensive
information (and the passion) are remarkable.

More re Stonogobiops; now symbiotic shrimp matching, comp.
w/ other livestock 10/1/13
Sorry to keep bothering you, my pair of high fin goby's have taken up
residence In the Jawfishes old home, and they are being very timid and
not coming out for feeding
I was thinking of getting them a pistol shrimp to help with
digging but was wandering what type of pistol will pair with them? We
have a pair of mandarins, 1 Jawfish, and 2 bicolour blenny's.
<... I'd very likely skip placing an Alpheid here... Too likely (highly)
to have trouble, even if the Pistol is commensal to mutual w/ the
Stonogobiops (nematodes BTW, not yasha)... You can/could look up which
species are found "naturally" together... The real trouble is size of
the system AND the other fishes here. Too much probability that the
latter would/will "get punched"... Keep reading. B>
Pistol shrimp issues; non-compatibility of currently offered
I was browsing your site looking for other information when I thought I
would check out the information on pistol shrimp. I found there lacked
some crucial and important distinctions in the information provided.
Lately there has been a flood in the pistol shrimp market of shrimps
belonging to the *Alpheus armatus* species complex. These
shrimp, despite what most LFS say, rarely play nice with gobies as they
naturally host with curly cue anemones. This has been giving a
lot of people and gobies unnecessary grief. People need to know that not
all members of *Alpheus *are goby lovers
* *and trying to force them into this unnatural relationship may end

about a month ago I decided to add the red banded pistol shrimp and an
aurora goby, 4.5 inches. (Ruby) The first day she jumped into the
overflow somehow and Wormburner the pseudo messed up her tail pretty
bad. I rescued her and she was fine, but a week ago, she Lawny the
blenny started chasing her. It all started when the green clown goby
finally got enough courage to come out and scoot around.. I saw Lawny
chasing the Aurora Goby, and the goby seemed tired, Lawny was just
biting her back repeatedly when she stopped, Then the next time I
looked, I couldn't find her anywhere. Until the next morning... she
had jumped out the hole for my Air bubbler hoses... she was crispy. The
pistol shrimp is still digging away. He is in the same corner as the
Black Ocellaris, Green clown goby, and the one spot blenny, it
seems Lawny has claimed the rest of the tank. Lawny allows the shrimps
and the Trapezia but loves to pick up crabs and swim with them. The
Clownfish are becoming more territorial recently.

Lost my Randall's pistol
Greetings again, crew.
It seems like lately I've sent you more e-mails than the rest of my
address book combined, and you've been a wonderful help.
<It's a pleasure!>
About two weeks ago, I purchased a Yellow Watchman and a Randall's
Pistol shrimp. Both were quite small, the goby being about 1.75 inches,
the shrimp about 1.25inches. I drip acclimated both of them, who stayed
practically glued together the entire time in the bag, and introduced
them into my system...and may have sabotaged my viewing pleasure of
Upon entering the tank, the shrimp immediately took off under my live
rock. This is supported by a single piece of egg crate, to help keep it
from digging down in the sand bed. The goby stuck to the corners of the
tank and milled around a bit, but didn't take to "hiding"
anywhere until the lights went out at night. In an attempt to coax him
to a place I could enjoy him more, I took a piece of PVC and crammed it
down in the front right corner of my sand bed, creating a nice little
den for him. He took to it right away, and now I get to enjoy watching
The shrimp, however, has disappeared somewhere under the rock.
Potentially, he may have been pretty frightened by my Coral Beauty
taking a curious nip at him when he was introduced. Despite giving his
buddy a shelter, I have yet to see him, though I've searched during
daylight, dusk, and night time hours. I've neither seen nor heard
him, though I notices that there are shallow spots under the egg crate
base of the rock now.
<They do tend to hide out of sight. What other fishes/ invertebrates
do you have? Anything that might cause problems other than the Coral
I at least thought I would hear him "snapping" by now. Is
there any way to lure/trap him to see if he's even still alive in
<Mmm, not really without ripping up your structure. I suspect that
he may still be in there, you could try the 'inverted bottle
neck' trap, but I do not have much hope that it will work here. An
alternative is to try moving the pipe that houses the goby more in
towards the rocks, or have a good search in there yourself>
Pairing Tiger Pistol Shrimp 8/8/10
Wet Web Media,
I have a Yellow Watchman Goby Paired with one Tiger Pistol Shrimp,
*Alpheus bellelus. *I have an intricate PVC pipe system that these two
inhabit. I was wondering if I bought another Tiger Pistol Shrimp and
set him at the entrance of the PVC burrow whether my current Pistol
shrimp would be inclined to allow the newcomer in. Is it possible to
pair Tiger Pistol shrimp?
<It is... but can be a tricky proposition... I would only do this if
there is sufficient room (like four square feet plus of bottom surface
area) to accommodate two separate burrow sets, animals>
If so do I need to distinguish between male and female shrimp?
<Can be helpful, but not necessary>
Or take the Clownfish route and simply add a much smaller Tiger than
the one I currently have?
<A reasonable approach IMO/E>
I know these things are never 100%, I am just curious whether anyone
has any experience regarding keeping two Tiger Pistol Shrimp in the
<They can/do live as pairs mostly in the wild.>
Seeing Double - Yellow Watchman Gobies Goby compatibility
Hope you are all doing well on this fine Saturday morning.
<Not bad actually,. just got my DIY Sulfur Denitrator online>
I don't know if I have a "problem" or not, so I wanted
Two weeks ago I added a juvenile (1.75") yellow watchman goby to
my 85 gallon reef tank. The first night the watchman disappeared, went
into the overflow, and was found the next morning in a filter sock in
the sump, alive.
<Glad he made it.>
I put him back in the tank, covered the overflow (it is already covered
with eggcrate and screening - this fish got through a 1/4"
opening) as best I could, and hoped for the best. Sure enough, that
night, the fish swam up to the overflow and was laying on the
screening. I thought it was dead, held it in the cup of my hand, and
poof! It twitched wildly, and literally flew out of my hand. I had NO
idea where it went. I didn't know if it flew back in the tank, over
the back or side walls, or on the floor.
It was like a magic act. I searched EVERYWHERE.
<Fish rule of anti-matter, a 1 inch guppy can vanish from a 1 gallon
fishbowl and never leave a trace.>
Fast forward, two weeks later, no sign of the guy. I assumed he was
dead (this should tip you off right here).
<Heheheh. Yes, I've been surprised by critters in my tank that I
thought were long gone.>
Yesterday, I added another juvenile yellow watchman goby. Guess what I
woke up to this morning? Two little yellow watchman gobies, side by
side behind a rock in the bottom of my tank, tails wiggling, looking at
me like a pair of prairie dogs.
Can these little gobies live together in my tank?
Will they fight,
<Maybe a little.>
and become a mated pair, or simply coexist?
<One or the other.>
Right now, they are glued to each others side. Also, my reef is not
something I can take apart to get one out. It would be a virtual
<Enjoy them. They really do better in pairs.>
Please let me know your thoughts and thanks in advance for your

-Goby shrimp w/out a shrimp goby!- Crew Person: <Kevin
person here tonight> I was able to get a "paired"
Randall's Prawn Goby (Amblyeleotris randalli) & Pistol
Shrimp. Unfortunately, a week into QT, the Goby
died. Now I am sitting here with a pretty expensive shrimp
(that looks more like a lobster). Anyway, my question is
this: can I get another fish to pair up, or am I up
shrimp's creek without a Goby? <Haha, I suppose that would
depend on the goby. Shrimp/goby pairs are actually very easy to set-up,
so I hope you didn't pay too much for the luxury. I would just get
a hold of another Randall's (after making sure what happened to
this one won't happen again) and you've got a pretty good
chance it will pair up. Make that a 95% chance.> It doesn't
sound likely, but I had to ask the pros. If the possibility
exists, can I get any species of shrimp goby, or stick with
Randall's? <The Randall's are pretty promiscuous as far as
shrimp are concerned, so I'd go with that one. Good luck!
-Kevin> Thanks for all you do, Rich.
- Uninvited Guests, More Follow-up - Hi, I setup my tank
about 3 weeks back, the night before setup, I discovered lots of pistol
shrimps. It was nightmare for me. It is now ok, took care of the
problem. <Oh... ok. Well, thanks for the update but do bear in mind
that pistol shrimp aren't generally considered "harmful"
and do have a role to play in a functioning ecosystem. Cheers, J --
Pistol shrimp/goby joy 8/13/07 Hi guys. For
once this isn't a panicky question about an aquarium disaster. We
just wanted to thank you for all the information on the site about
shrimp gobies and their shrimps. We (rather naughtily) bought a
"tangerine striped goby" from our LFS yesterday, having gone
there intending to buy a Copperband (they didn't have any).
Admittedly, this goes against your golden rule of never buying anything
on a whim and without reading up on it first, but our trusted LFS
manager said it should be fairly easy to keep. We got him home and
found that he's really a Randall's Shrimp Goby, did a bit of
reading, and decided we'd try to find a shrimp to keep him company.
Today we've brought home a tiger pistol shrimp, and within an hour
of putting the shrimp in, the two have become completely inseparable.
It's amazing to watch, and the shrimp is very entertaining to watch
as he tries to build a burrow. Just felt we should share this with
someone! Jim+Jo <Greetings. A while back I kept a whole tankful of
snapping shrimps, and it was one of the most fun tanks I've kept.
It's funny, but things like snapping/pistol shrimps and mantis
shrimps are often written off as pests by reef keepers, but when the
focus of their own tanks, become engaging pets. Snapping shrimps are
incredibly hardy (these were, at least) and because of where the tank
was set up, water changes were something that happened once a month, if
that. It was the most basic aquarium imaginable: undergravel filter, no
chiller (these were coldwater shrimps), and certainly no skimmer or
living rock for water quality management. But they thrived! I can't
be sure if they bred, but they certainly grew, and their numbers seemed
to remain steady. The noise that came from the tank was quite eerie
sometimes, like crumpling leaves. Anyway, all this is by way of saying
I'm glad you're trying something a bit different, and wish you
every success with your new pets. Cheers, Neale>
