one of my emerald crabs came to the front of my tank, up against the glass, it would appear to be eating as he moves his mouth, but he won't move from its place since last night... Is he sick?
If I get my hands in there, he seems to react and try to move about an ich in the opposite direction, but then he stays stagnant yet again.
_BTW, I saw a video on YouTube of some guy feeding a Mantis Shrimp with an Emerald Crab, and I thought that it was merciless. Not my type of Shrimp. they do have beautiful colors though...
Here it is...(Warning, it's very National Geographic)
try feeding hi with a piece of shrimp or something, if he'll eat he is probley ok. is strange for him to stay in a spot like that in the light, mine hide mostly in darker areas if they are out during the day.
