Help with ID

I work at a LFS , and on our last shipment of liverock we found all sorts of interesting things... I like to look through the bottom of the box after the rock is removed, because there is always an interesting assortment of creatures crawling about in the bottom of the boxes. Anyhow, amongst thee crabs, worms, and other strange reef dwellers, we stumbled across a mantis shrimp. My co-workers put him in a bag with water and were showing him off throughout the day. When I saw him, I thought he was really cool and asked if I could have him. They couldn't really figure out why I would want him, but agreed anyways.

I'd have to say that he is about 3/4" long, and mabey 1/4 across. He came in on a shipment from Jakarta and i'm sure that will help in the ID. I looked at the ID thread posted at the top, but i'm not sure that he looks like any of those.

The other thing I am wondering about is his behavior.(SP?) He lives (temporaraly) in a 1 gal kritter keeper with a tiny powerhead for areation, a small chunk of live rock, no sand, and as of yesterday, an 7.5w HYDOR mini heater. The first 2 days I had him he crawled into a hole in the rock and was chillin in there. On the third day ha came out of the rock and was lying upside down on the bottom. I thought he was dead, but an inspection with the maglight proved that he was still wigiling about ans curling his tail up around himself. He was like this when I got home from work, so I decided that mabye the water was too cold, so I added the heater. 24 hours has passed and he's still upside down on the bottom. He looks like he might be eating from the water coulmn, so I dumped a bit of marine snow in there, and yesterday he took flake food from me. Could he be molting, is it still too cold(don't actualy know temp, i'l find out after I get a thermometer from work tomorow) does he want sand, or more rock, or... I'm stumped.

Any help would be apreciated, Thanks!

The animal looks like it is on its last legs. Don't expect it to live. Once they deteriorate this far, the damage is usually irreversable.

I can't see the dorsal telso, but my guess is Gonodactylellus viridis.

Yeah I wondered if he was on his way out. He did spend over 24hours in a bag after being shipped overnight with no water in the liverock, and then into an unheated 1gal for 2 days.... poor guy, I just couldn't set anything up faster than that to house him. Well if he dies mabey I'll try to get another one. They really are facinating creatures. I still hope he pulls through somehow though!
 
RIP little mantis

RIP little mantis

Well, sad to report that as of 12:12am on Wednesday march 22, 2006 my little hitchiker mantis has passed away. RIP little guy.

I will not give up though, I have become rather intrigued by these creatures, and will continue setup of the new tank in anticipation of getting another mantis...
 
Ok, finalpost here. I am still kinda curious as to what I had, so I took a few post morteum pix. Mabey theese will help with an ID of the shrimp, just in case I run across another in the liverock bin.

I figure he most likely died of stress or a related cause due to his shipping and aclimation conditions as well as my dificulty in keeping the salinity in a 3/4gal system stable... I tested when I pulled him out of the tank, it was at 1.030, up from 1.025 this morning before work...
 
Well, at least now we can get it to family. It is definitely a gonodactylid. I can't tell much more than that. It reminds me of one of the species in the Gonodactylellus hendersoni group, but the spine on the top of the telso suggests it could be a Gonodactylopsis. Sorry, but I cant tell you more than than.

well thanks for all your help with this. I really apreciate all the info, after all, learning a new thing in the hobby every day is one of the things I enjoy most about it.

I have a 2.5gal tank that I was setting up for this guy. It is going to be plumbed into my main system. the 2 questions I had were, how much flow do they like, and what would be a good shrimp to live in that tank? I was excited to learn that the green mantis stayed at about 2 ". I am going to see if work can order me something, and if not then I'm just going to dig through th LR bin one of these days.
