I was camping for a couple of days and came home to this on my pineapple betta, Maui. Does it just look like an injury to you guys are something else. I like to get 2nd opinions. . @Colin_T what do you think? He’s in a 5G with weekly w’c’s and cleaning. PH 7.5, GH10, KH6, ammonia 0,nItrite 0, nitrate 20 (cleaning day tomorrow.). Just noticed filter quit working too so gotta go get a new one.
