need help identifying crab....


New member
I apologize in advance for not having a photo, but i found a crab in my tank the other day and i need some info on it. it looks exactly like a fiddler crab (same size and structure) you see in fresh water tanks but it is red. there is no brown and the crab is about 1-1.5 inches across. like i said it looks exactly like a fiddler crab. anyone seen something like this before?

Fiddlers aren't strictly fresh water, they can occur in brackish and even saltwater, most often in mangrove forests and sometimes in shallow tidal pool areas. I know that some places sell them, but I've never actually heard about them getting into a tank without the owner know!
