hi, I just found one of my albino corys stuck in my sponge filter. He appears to have injured his side and it’s red like it’s been/is bleeding. I think I found him pretty early as he’s still relative active but seemed to be stuck on the filter. I’ve isolated him but what can I do to help? Can I use API aquarium salt to help with healing? Is all I can do wait and see if he makes it? Thank you so much for any help!!
