My boyfriend's halfmoon, Enigma, has fins so overgrown and huge that they weigh him down and make him lean over when he rests. He has a hard time swimming and always looks exhausted when he comes to a stop after simply going from one end of the tank to the other. He lives in a filtered and heated 2.5 gallon with live plants.
Is there anything we can do to help him? He's always had a hard time swimming since his fins grew tremendously. I've heard of fin cutting before, but we're both too nervous to do it.
