I've got an Anglefish, that looks like it's on the way out, but just seems to keep hanging on in there.
About a week ago it started to behave differently. It started to hang in one place in the tank - directly into of the filter outlet. Then things developed to a point where it just lay on it's side on the bottom of the tank.
The day before yesterday, I put the fish in an isolation tank, and have started to treat it with both melafix and pimafix. It's still hanging on in there, but is laying (99% of the time) on it's side at the bottom of the tank. It occasionally makes an effort (and it does seem like an effort) to move and will swim upright to another part of the tank then drift back to the bottom. If the fish is disturbed, it tries to move. It doesn't seem to be feeding. There are no obvious wounds, but it's pectoral fins look a little shredded.
Apart from the symptoms I've described, it rarely seems completely still - a fin waving, mouth opening slowly, occasional twitch. As I've said, it seems to be hanging on in there, but I'm at a loss. Any improvement since I started medicating is VERY minor.
Anybody got any suggestions?
