I noticed his gills are like pushed back exposing his pink little fish insides. For a few days in a row now I've had to catch him and cut the pond weed that has been sucked in his mouth and gone out his gills and bck to his mouth. I was hoping his exposed gills had sonething to do with that but he's not getting any better. I just moved into this house and I have no idea on how to care for fish. What could the problem be and what can I do to help him?
