I have a fiddler crab, one of the ones with two different sized pinchers, and I need the tank he's in for the plants we had in our outside pond. I don't wanna just get rid of him, because who wants a crab, and I can't kill him or flush him, the poor thing. I was wondering if he would be able to go in with any of my other fish. I have a 55 gallon with African Cichlids and a 75 gallon with Oscars. I also have a 10 gallon with assorted fish like a tiger barb, guppies, neon tetras, stuff like that. If he will kill any of the fish or if the fish would kill him, I will just try to find a new home for him. He's about an inch long and his big pincher is maybe 2 inches...
