emerald crab

[fishguyxd]

Well last night i had a healthy emerald crab and tonight he was laying on the bottom (dead) legs up and looking the same color as coroline algea I have had it for a few months and no problems the only thing is i can say that was different with the tank was the temp it went to about 82 ish and i threw in a frozen shrimp for the local store last night as a treat for all.

I had something like this a couple months ago when i lost 3 zebra crabs
same situation minus the temp problem due to me not having lighting.

any suggestions ??
