Hi, I have an established 72 gallon tank with 4 various parrots. Last week i saw a “platinum” parrot at my LFS which I had never seen before. I fell in love with it and bought it exactly one week ago. I am assuming it is a male because it has a small nuchal hump and it immediately “clicked” with a small female in my tank (I know its a female because she has laid eggs before). The female stuck up for the new fish and I feel she really made his introduction to the tank easier as she fended off the other fish from him. Everything was going great but I did notice he was not eating as aggressively as the other fish. I contributed this to non familiarity to the food I was feeding them but did notice him eat a few pellets. Today I woke up to find him upside down in the tank with what looks like maybe a prolapsed anus. He is still swimming but remains upside down for the most part at the bottom of the tank. I put some salt in the tank and raised the heat, thinking it might be either a swim bladder infection or constipation. This evening I notice what I can only describe as pink tentacles coming out of the anus. They come out, they go back in and they seem to move on their own accord. Please see the video / pictures and tell me what these things are. I have vast aquarium experience and the parameters of the water are perfect. Any advise would be greatly appreciated!
