Another Shrimp Goby Question-12/22/2007
Hello Crew,
<Paul>
Thank you for all the help as I now have a full blown reef going great with minimal maintenance. I have been researching for a long time now and still am not sure about which goby is most likely to form a symbiotic relationship with my pistol shrimp. The species of shrimp I have is the exact same as pictured here
_http://www.bluezooaquatics.com/productDetail.asp?cid=84&pid=1215&did=2_ (http://www.bluezooaquatics.com/productDetail.asp?cid=84&pid=1215&did=2)
an Alpheus species.
<Mmm, notice that the ad states this animal is from the Caribbean?>
I have narrowed down the list to yellow watchman (Cryptocentrus cinctus), High Fin Goby (Stonogobiops nematodes), Flaming Prawn Goby (Discordipinna griessingeri), or Yasha Hase (Stonogobiops yasha). Am I correct in assuming Indo Pacific is considered Caribbean or am I totally in the wrong ocean?
<... the latter>
I have tried fish base but when searching such a generic area as "Caribbean" it is not very helpful. Any suggestions? Thanks in advance.
Paul
<Well... there are in-print works on naturally occurring relations... And Alpheids can/will often pair up with "dissimilar" symbionts... I would go forward with the choices of fish hosts in the order of preference you list. Bob Fenner>

Pistol Shrimp/Goby Pair?   7/19/07
Hi crew
<Hi Adam! Mich here.>
Question from Australia :),
<Cool... Answer currently coming from the Pocono Mountains of Pennsylvania, USA>
I will definitely be getting a shrimp/goby pair for my 24x18x18.
<An awesome dynamic to observe!>
I was wondering if I could have 2 pairs?
<I would look for a mated pair of gobies and their symbiotic shrimp. This is the best situation>
different sp.?
<You may be OK with different species. I would avoid getting two of the same species unless they are a mated pair.>
have read a lot on these symbiotic relationships and really like them.
<It is quite captivating... Hours of entertainment!>
Also finding a suitable substrate. The opinions differ again. Is it species orientated?
<Each individual fish can be different. Best to provide a variety of options. I would place a couple of small piles of rumble of varying degrees of coarseness about the tank. You will also want to make sure you live rock is placed directly on the glass and not on the sandbed as any borrowing fish could be accidentally crushed. And you will also need a well cover tank as these Gobies can be jumpers.>
This is the whole aim for this tank, to have a shrimp/goby symbiotic relationship.
<Very nice! You will surely enjoy!>
Only keeping soft/LPS corals and fish that will live in harmony with my shrimp/goby pair.
<Very good!>
Thanks
<Welcome... If you write again please don't forget to use proper capitalization. Mich>

Seahorse tank set up/sand sifting gobies   7/17/07
Hi!
I am in the process of setting up a 56 gal. tall tank for seahorses. I am in the cycling stage right now and only have the substrate (CaribSea Arag-Alive Indo-Pacific black ) a protein skimmer and a refugium with live rock on the tank (will add algae end of the week). I also added Turbo Start 900 to help seed the tank and speed up the cycling process.
<The LR will do this...>
After my water is correct I will begin to add copepods to the tank and refugium and then livestock. How long should I wait to add the livestock after the copepods?
<A week, few weeks>
I am planning on adding snails (Cerith and Nassarius) and dwarf blue legged hermits to be a clean up crew, and I would like to add a sand sifting goby to keep the sand nice and clean.
<Mmm, not much surface area here... will likely keep the system "too clean" of the copepods...>
I am not planning on putting any live rock in the tank-just some fake corals to be used as hitching post for the seahorses. What would be the best goby to use and when is the best time to add it to the tank? I like the V. sexguttata
<http://www.saltcorner.com/sections/zoo/fish/gobies/Valenciennea/Vsexguttata.htm>Sixspot
Goby, and V. strigata
<http://www.saltcorner.com/sections/zoo/fish/gobies/Valenciennea/Vstrigata.htm>Yellowheaded
Sleeper Goby, but I am not sure if either of these are the best choice for my tank.
<I would not place a genus Valenciennea goby here... again, too big for the amount of substrate...>
I've read that you should keep a pair (M/F) of both of these species of goby as they do better, how can you tell what sex they are?
<Much happier in pairs... but you don't have enough room>
Thanks for the help. Your site has been a great help to me in the past.

<Likely the Hermit, Nassarius species will do about all that can be done to turn, clean the gravel here. Bob Fenner>

I forgot to mention that the skimmer is not running right now. I will turn it on with the addition of livestock.
<Real good. BobF>

Watchman-Pistol Question
Dear Bob:
You have been so kind in sharing your knowledge with me. I have one more question before I buy my Yellow Watchman Goby and (Tiger hopefully) Pistol Shrimp. Do I need to buy an already established pair, or would any Watchman pair up with any Pistol Shrimp? I don't want to buy them and be disappointed if they don't "pair up."
Thanks, Janey
<Better to buy them together... but they do often "pair up" in captivity as well. Bob Fenner>

Gobies and shrimp
Hi Robert, I'm sorry to email you here, but I don't know how to post on WetWebMedia.com. I hope you can provide guidance:
<Will try>
I want to buy a pistol shrimp and Goby. I have my eye on two gobies. One is the Stonogobiops nematodes. I read on your site that he would most likely pair up with the Alpheus randalli. I can not find the everyday name for this shrimp.
<"Randall's Pistol Shrimp", named in honor of Dr. John (Jack) Randall of the Bernice P. Bishop Museum>
Is it just a common pistol shrimp (I have a friend who wants to sell me his pistol shrimp)?
<Mmm, I consider none of these to be "common"... all species are hard to come by in the trade, hobby.> 
-not sure if its a wise move on my behalf)?
<Know nothing about wisdom>>
The other goby that I am considering is the Pinkbar Goby (Cryptocentrus aurora). Do you know which shrimp he would best pair with?
<There are lists of which species are associated in the wild... Often, captive conditions can form "strange partnerships" though>
Is there a general rule of thumb for encouraging symbiosis between the two?
<Lots of space, good husbandry, mix of fine sand and rubble of depth, peaceful tankmates...>
What is the best way to ensure symbiosis if you cant but the two already paired up? 
<Buy them together, evidencing their association in advance>
Do you have any recommendations for which types to purchase for a small (30 gallon) set up?
<Mmm... please read through the "Shrimp Gobies" section and related/linked files on www.WetWebMedia.com>
Would I have to get rid of my decorator crab if
I got a P. shrimp/goby?
<Possibly... if the system is small... the crab hungry, could be trouble.>
Thank you once again Bob. Your time and effort for all of the work that you do on your webpage is much appreciated.
<Thank you for your kind words... many hours of my own, friends devoted as you state. Bob Fenner>

Shrimp question
Hi,
<cheers>
I just got a yellow watchman goby for my tank. How do I put a shrimp with it, and which shrimp do I get? 
<commensal pistol shrimp generally must be collected with their watchman goby to be compatible. Even when that is not the case, one usually needs to match the exact natural partner species with the goby. You need to get an accurate scientific name for your goby first... then research the commensal species for this goby. It is very unlikely that you will be able to find a compatible match without having obtained a collected pair.>
My tank is a 38 gallon with only fish, and a starfish. 
Thanks, Dyanna
<do tell us if you find a species that works. Kindly, Anthony>

Randall's goby with lawnmower blenny
Hi,
Thanks for the great site, I send lots of people to it.
Normally I can find my own answers, but this time I want yours.
In a 37 Gallon " oceanic corner tank" I keep 25 lbs liverock, four inch deep sand bed. Fish are a pair of percula clowns pair of yellow  tail blue damsels, and a lawnmower blenny, with about 10 mixed snails, 10  blue leg hermits, and 6 asst mushrooms. Recently a friend gave me a 1 inch Randall's pistol shrimp. All is fine 2 weeks later, and I am wanting to add a Randall's goby or a yellow watchman goby. In this set up, do you think the goby and blenny would get along?
<I give you good odds. Salarias, Atrosalarias blennies are generally only feisty with algae eating competitors>
And if so which goby would be a better choice? Tank has been set up a years as is now.
Thanks for any reply, Roger
<The Randall's if you want to see interaction with the alpheid... The Watchman if not. Bob Fenner>

Re: Randall's goby with lawnmower blenny
Thanks for the quick reply, I keep an emperor 400 and the live rock, DSB for filtration, forgot to mention the emperor 400,again,  thanks.
<Sure, No problem.  I would suggest a protein skimmer if you don't have one already.  MikeB.>

Watchman Goby
Hi,
We have had a Yellow Watchman Goby for about 6 months. She was very small when we got her - is now about 1 1/2". I feel sure it is a female because the coloring of her body is much duller than her face (creamy yellow instead of bright). We would like to get her a mate, but the LFS doesn't carry them and you can't specify sex when ordering online. If we ended up with 2 females, would they fight?  Thanks, Doug
<Hello Doug. They won't fight, but they won't be hand and hand such as clowns. James (Salty Dog)>
