Can anyone help with this Betta illness? It looks like his whole gill has rotted away. It’s been going on for a few weeks. I started treating it with aquarium salt and Paraguard. That seemed to slow it down a little but didn’t get rid of it. I went to a local fish store and they recommended polyguard. We’ve been treating for 1 week with that and he still looks rough, now it almost looks like there are strange growths in the area. Does anyone else have any recommendations? Attached are a few photos taken during his treatment.
