Hey everyone, so I noticed today that my betta has some sort of growth near its dorsal fin. As the pictures show the growth is very round and white, it does not look fuzzy. I think it is some sort of growth or tumor but I am not 100% sure. My water parameters are pH 6.5, KH 0 ppm, GH 200 ppm, Nitrite 0 ppm, Nitrate 10 ppm, Ammonia 0 ppm, Temp 80 F. The tank has been up and running for about 4 months now. Any help identifying the issue and possible solutions would be great thank you!
