My p.elongatus in my cichlid tank seems to have developed a hernia It looks like some of his guts are hanging out of his anus. Apart from that, he seems fine, swimming around, eating and making a general nusiance of himself, as usual. The water parameters are good, no ammonia, no nitrite, low nitrate and no other fish are affected. Could it be a problem with the food swelling in his stomach and forcing his guts to move? He's now one of the smallest fish in the tank (from being the largest and a bully) but he insists on eating the larger granules that the others eat. I do put smaller granules in for him and a few other smallies, but he doesn't want to know. What do I do, leave him and see what happens, medicate the tank or what? Help please.
