my new poor little albino cory got stuck on the filter a couple days ago.. hes the smallest one and I know the pull from my filter is pretty strong because ive seen some of my mollies get pulled onto it but they’re always able to get away, I didnt think this could happen. I feel horrible, he was wiggling all over the place trying to get free. I turned it off and he swam away and I thought everything was okay. since then hes just gotten worse.. he is currently laying on his side, he moves only if another fish comes too close.. the only damage I can see is a rip in his fin. I did a big water change. is there anything else I can do for him?
