Saron marmoratus shrimps
Hello everyone!
<Hi there>
I just bought two shrimps « Saron marmoratus » for my refugium, from the look of them I would say they are both females.
<I have never seen males sold in the trade... quite different, much longer "legs">
I don't usually buy a creature that I don't know about, but when I saw them, I couldn't resist. I read everything there was on your site and some on the web, but I can't find a site than would say more than half a page. And they don't even say the same thing from one site to the next. 1 to 3 inches, reef safe to not reef safe, aggressive to Gets along fine with fishes and other crustaceans. 
Since I put them in my refugium with only pods, algae and one hermit crab (Should I transfer the crab in my tank?) I think both Saron shouldn't cause to much problems. 
<Mmm, I'd say not "very" reef safe... can/will at least walk over corals... will eat other crustaceans, mollusks, worms if hungry>
And now for my request (Asking with lots of pretty please) could you direct me on a web site than devote more that a few words on them.
Thank you for your time.

<Don't know of such a site... perhaps a visit to a large (college) library, a search of the literature there... But am pretty sure that you will find there is precious little written re the genus's practical husbandry... With good notes, photographs, you could write such up... Bob Fenner>

Saron shrimp
Hello to all of you who are a lifeline to those of us who are saltwater aquarium enthusiasts and a big thanks. I have read all the books written by Mr. Calfo and Mr. Fenner and loved each book. Full of great information. Now for my question. I have a 55 gallon SW aquarium with a big fat yellow tang, a maroon and gold clownfish and a coral beauty, 2 skunk cleaner shrimp, 2 blood shrimp, 3 peppermint shrimp, featherduster, Sally Lightfoot, various snails for cleanup purposes. I recently purchased a lovely large colt coral and it's been doing great but something is taking big bites off the branches. I had a big arrow crab that had overgrown my tank and he was hanging out in that area so I blamed him and since he really had gotten much too large for my tank, I gave him to a friend. Last night I got up to see if I could see anything else that might be the culprit, though since giving up the arrow crab I have not seen any damage, I saw what I think was a Saron shrimp hanging out in that same area. I knew that shrimp was in my tank, came in as a hitchhiker with some coral but he had never caused any trouble whatsoever and he is hard to find and very hard to see since he blends in so well with the live rock. Anyway, will these shrimp eat corals? I know they are carnivorous and aggressive but have not had any death in my tank and because he is sooo hard to catch, have let him be.  He was sitting on a rock with yellow polyps on it. Should I assume this shrimp to be the culprit and tear my tank down to catch him? I have a lot of coral in my tank and do not want it destroyed. I  have soft corals, zoanthids and mushrooms in my tank. I have lots of live rock so trying to catch anything is just about impossible without causing an avalanche. Thanks in advance for any helpful information you can give me. Oh yes, one more thing. I have just purchased a canary wrasse to help control the bristleworm population. They give me the creeps. The arrow crab was SUPPOSED to do that but he would not eat a bristleworm if you dangled it in front of him.<Yes, they are not known to be big bristleworm eaters although some aquarists have witnessed it.> LOL. I try not to overfeed and have a Remora C skimmer that does a good job. I can't even trap a bristleworm so I don't think I would be successful in trapping this shrimp. Once again thanks so much to all of you who give your time so willingly to contribute to the success of this wonderfully rewarding hobby. <Janiece, I believe the Saron (Marble shrimp) is the culprit.  They are not reef safe and are harmful to some corals and other invertebrates.  I think if you got a mantis shrimp trap and bait it, then put the trap near him, you might have a shot at catching it. The only safe coral with this shrimp would be the leather coral.  Good luck trapping.  James (Salty Dog)>

Saron shrimp: reef safe? Nope 1/30/04
Hi! I am planning to get a Saron shrimp and I checked your website for more info on Saron shrimps, but I couldn't find anything that says whether they are reef-safe or not, as I've received mixed opinions on them. So, may I know whether I could keep this shrimp in a reef-setting without corals getting pestered.

<an easy one, mate... Saron shrimp are categorically un-safe with benthic invertebrates. They are generally opportunistic and commonly attack bivalves (including Tridacnid clams), harass other bottom dwelling fishes and invertebrates. And frankly are opportunistic scavengers/bullies. Anthony>

Green Hawaiian Shrimp
I am considering purchasing a green Hawaiian shrimp with my next order.. But I can't find any information as to compatibility with tank mates... Anything I should take into consideration.. I have a little bit of everything in my tank... feather worm, sea apple, Brittlestar, starfish, tangs, damsels, mandarins, clowns, Foxface, shrimp, snails, crabs, etc.. Please give me some info on this shrimp.. I have learned my lesson on purchasing without checking compatibility the hard way before.... Thanks, Leeann 
< Mainly if your livestock will eat the new Shrimp... not the other way 'round. What sort of shrimp and crabs do you already have?... If you have the mix you list and they're healthy, you're doing many things right.... the new Shrimp might bug the feather worm if it's really hungry... but may I point out the Sea Apple may be the biggest problem... on its own. Keep your eye on it... otherwise, I wouldn't worry about the Hawaiian one with. Bob Fenner>

Green Marble Shrimp?
Greetings Mr. Calfo,
<Greetings, Robert>
I have a 55 gallon tank. I currently have 2 Percula's and a handful of
Caulerpa. I would like to get your opinion on the following potential future inhabitants:
<thank you kindly for caring to know my opinion>
Hermit Crab
Green Marble Shrimp
Marine Betta
Will all of them get along? The green shrimp is classified as a carnivore but do they eat algae as well?
<not sure by the common name "Marble" shrimp...but wonder if you are referring to a Saron species (please reference). And the Betta is a great fish and one of the absolute hardiest and long lived fishes for marine aquaria (one of my favorites). However, shrimp are a natural food and they do eat small live prey (including fish and crabs). So in truth... there are conflicts in your targeted mix. I'd focus on a centerpiece, like the clowns, and work around them. As much as I like the Beta/Comet... they are shy and no fun <wink> by hiding in a cave all day. Get another hit list of more fish that interest you and pass it along, please. Anthony>
