help! I'm new to this website but along time betta owner. My betta scrappy, he's about 2 years old and he is a split tail. In between the split in his tail, he has what looks like tail rot. It looks like a white spot with pink in the middle. Its eating away at his body slowly. I clean the water at least 1 time a week and I put stress coat and aquarium salt in the tank. It hasnt got any better and Im worried. I dont think that bettafix will help me. any suggestions will be very helpfull to me. Thanks so much in advance!!!!!
