He lives in a 2.5 gal tank (which I’m hoping to upgrade once I move out of my dorm for summer break) he has a filter and heater running, water temp is always around 79-80 degrees. I do 20% water changes every week and treat it with BettaSpa.
He’s still very active and likes to lay on the plants. He also still flares and builds bubble nests. He’s gotten a bad habit of biting his fins (which I’m trying to get him out of) but other than that I feel like he’s acting normally for him to be turning white. I’m genuinely concerned and confused about the whole situation and I’m hoping to find out what it is so I could treat it and get rid of it as quickly as possible.
