I have a tiger barb that got stuck to the filter (came home and found him this way) My husband got him off of the filter, but now he is kinda bent and "floating" sideways... he's really not swimming, every now and then he'll use his fins, but he just kinda floats up and down the tank. What should I do? I dont know if he may just be recovering and I should just leave him alone, or what? help!
