I had a post on here before while I was trying to figure out what was wrong with my friends betta female. It turns out it's an Ulcer cause by jumping from her tank a few months ago. A patch of scales dried out and never got their colour back and simply stayed brown instead of turning green again.
Now she has this ulcer on her side that was red and bleeding which has now turned white. It hasn't gotten any better but she's still acting like a normal fish
She's in QT and is getting daily water changes along with aquarium salt and Maracide, Maracyn 1 & 2, but not altogether. I don't know what all she's giving her ever day. The fish isn't getting any better.
I've been doing research and I keep seeing people say to use a full dose of Melafix and it will help. But I also remember hearing awhile back that Melafix can kill a betta fish because it damages its labyrinth organ. Is it okay to give her Melafix or should we stay away from it?
