I have a 5 gal tank w/ a guppy and 2 cory catfish...all of a sudden today the smaller of the two catfish has a problem w/ one of his front fins, it looks bent, and there is also a very noticeable bite out of his tail fin. his color is also not very good at all....i havent seen the other fish bothering him, so i have no idea what happened and i dont know what i should do. He just keeps swimming around near the front of the aquarium. can i help him?
Here are pics of the bitten cory...
