Have had a male and female pair of apistogramma c. in a 15g tank for a few weeks to attempt to breed them. I have noticed though that the male has had this weird thing hanging out of his anus. It looks like some kind of big with little hairs that's kind of white and fleshy red. It's not poop because he poops and it's still there. I first saw it hanging out but now it seems further in. I think that it would be weird for the fish to have sex organs this large but I don't know this species that intimately. Is there a parasite that looks like what I described and how do I treat it?
