I noticed my Benis fins suddenly smaller and went on reddit to ask advice. Most people said it was fin rot so I did water changes like crazy, added an almond leaf and tried stress guard. I just started maracyn when I happened to stumble upon an article here about fin biting. Do you think that's what's happening here? I have the test kit and his parameters are good, he's in a 4 gallon (pending his condition to improve I have a 15 planted gallon waiting for him), he's 1.5 years old, eating fine, has only silk plants with him, he's alone in his tank and I've never seen him bite a fin. If so any advice? Should I move him right away?
