Hi ! So I just bought myself a baby Pepper Cory Catfish from Petco yesterday. After acclimating my Cory to the new water I finally released him into my aquarium. I left to go exercise and when I came back I saw that he lodged himself into one of the filter intakes. I stuck my hand in there to help and he swam out just fine. I checked to see if the suction might be too strong but I felt nothing. He seemed okay so I went to bed not worrying too much about it. The next morning I found him in the intake again, but this time he swam out with an injured fin it seems. It's still intact and I see no scrapes, but at the base of the fin there are two red dots. Now he swims around the tank with his one working fin and lays on the gravel on his side. He also swims upside down on occasion so I'm hoping that he isn't suffering from swim bladder disease. My filter is built into my tank, so I cannot go out and buy another one. I've covered up the intake with some sponge and I'm just hoping that he heals up okay. Is there anything I can do to speed up the healing process? He shares a tank with 5 other neon tetra.
