This has only happed today. 3 lots have dropped out today after I cleaned the tank. I’ve had the fish for 2 years and is around 10cm or 4 inches and lives alone in a 24L tank. The strange thing is that she hasn’t done any poo for a few months. Thanks for the helpProlapsed rectum. For how long has he had this, how long did you have this fish, what size tank is he in, what are the water parameters and how big is he?
His tank is too small for him. You would need 114 L per goldfish.This has only happed today. 3 lots have dropped out today after I cleaned the tank.

I agree. Many people make this bery poor mistake by putting large and messy fish in a small tank (goldfish) and hen wondering why they've got problems with water quality and/or sick fish.I'm afraid he's got issues due to being in a tiny tank (he's got the size of a 4 or 5 month old goldfish), there is not much you can do about it at this stage.
