That's one of the things I'm worried about is harming him from different medications. I just hate to lose him and it doesn't look like it is getting any better. I probably need to stick with frequent water changes at this point . Would aquarium salt be considered medicine and possibly have adverse effects or should I leave it alone and just stuck with water changes?hello; been there and done that. By saying this I mean I have had sick fish and took a shot at a treatment which did not work. So I tried some other treatment and after that another different treatment. Never sure if all the side effects of the treatments dis the fish in or if the initial disease did.
When I do not have a pretty clear notion of the problem I now try to keep things to a separate tank with good water conditions. Separate tank so the stress of being in a community tank is reduced.
Also if the fish does die then it will not be fed on by the other fish and this should reduce the chance of other fish picking up a disease by such direct contact. A small preventative measure but??
