bad news, good news

ok, heres the bad news first, i recently went on a trip to montana for a week, so i asked my friend to take care of my fish, cat, and mantis while i was gone. i wasnt really worried because he also has many fish tanks and a mantis of his own so i figured he knew what he was doing. well, when i came home i found him in my room filling up tanks. apparently he hadnt been to my house in a couple of days and my room got very hot and alot of water had evaporated in my tanks, especially my mantis tank, the salinity had rised up to about 1.035. so naturally he filled the tanks back up. ten minutes later my mantis was dead, he was a peacock by the way.

ok, heres my question of the day, we checked the salinity after the water change and it was 1.024, could a change in specific gravity kill a mantis shrimp? what else could it be, hes not an idiot so i know he diddnt just put tap water in there. so what killed him?

ok, so heres the good news, with a nice water change i was ready for a new mantis, now where i live there arent very many stroes around who would want to carry any sort of mantis. but get this, for some odd reason just about every store i went into had at least one. one store in particular had three peacocks and two unidentified green smashers. needless to say i was a bit excited by what i saw. i decided to wait a day or so. i already own a small green smasher and i had just had a peacock, so i wanted to see if i could get a different species.

thats when it happend. an monday i walked into a shop i dont normally go into. its one of those whole in the wall places that sell illegal stuff out the back. i dont like going there but i know a guy whose a manager there and he knows what i like to keep so he saves some things that pass through. anyways, i go in there and he comes up to me and says "you gotta see this" so i come over to this little five gallon glass tank, i figure no way it could be a mantis, hes smart enough not to put it into a glass tank. but i was wrong, it turns out that he got his hands on a 2 inch yellow green pseudosquilla ciliata. if your not surprised, it might help to emphasis how long ive been waiting for this, at least 5 years for one of these to show up in a local store.

ok, so hes not home yet, the guy at the store made the mistake of putting him in a huge chunk of live rock and now hes battling him trying to get him out, he says hill call me when he has it seperated.

so thats how my weeks been.
 
O.s. that are slowly acclimated to salinity change can live for days at 1.035 although eventually it will do them in. The combination of high salinity plus temperature was really stressing the animal. If the salinity was dropped to 1.024 in a matter of seconds, the osmotic shock probably ruptured the gill flliments and did the beast in. Temperature shock could also contribute.

Pseudosquilla ciliata are actually closely related to O. scyllarus and have basically the same temperature and salinity requirements although P. c. frequently are found in the low intertidal and you would think would be a bit tougher. In my experience, they are similar in their ability to tolerate abuse by aquarists.
