Crab w/Fans = Porcelain?
I just found a crab in my tank that I think is a porcelain crab. It has large pinchers relative to it's body (about 1/4"-1/2" body dia I'd say), but it was hanging from a crevice in a rock while two "fans" were waving around in front of it's head, looking like it's collecting food from the water?
I use DT's in my tank to feed a clam that we have, even though long-term I think the clam will die in our tank (not intended as a clam tank).. so maybe the crab is eating that DTs?
Is a Porcelain crab the only sort of crab with these fans? Are these crabs OK in a tank? Most seem to think they are OK but I'm not sure. Those pinchers are pretty darm big.
