Hello. I got one black molly yesterday for my brackish tank, and today, a bit of its dorsal fin is missing, about 1/5. It is housed with two red claw crabs and 5 ghost shrimp. Do you think it was the red claw crabs? It's pretty healthy and it happened overnight so I'd rule out fin rot. What should I do?
