arrow crabs

yes they do eat fish when bigger but for now they llike eating bristle worms.....

Maybe give it some shrimp tail tips for raw material to produce its new shell. I think iodine is also supposed to be needed for good molts (at least with shrimp it is). If the crab survives till the next molt, it'll be fine.

they go after fish and fingers... didn't last long in my tank after stabbing me

We had one for a while but the moment I saw him pulling a hermit crab out of it's shell, the arrow crab was banished to the sump. Too bad though, I think they are the coolest looking crab!
