Hey everyone, I have a fancy goldfish in a 5 gallon tank, it’s been doing well untill 2 days ago it got a bump, I did a water change and cleaned the tank, it shares the tank with a Pleco, after the water change the fish was acting healthy and was swimming and eating, this morning the bump was bigger and has white stuff coming out of it, did a 30% water change, my mom did the water change and said the fish got stuck in the suction tube but she got it out, it was bleeding from the bump and now is still swimming and acting normal. This keeps happening, is there something we can do to prevent the bump? What causes it?
