I recently bought my flowerhorn about two months ago, he is very active in his tank and is eating a lot. However recently he started to get these circles on his body. I contacted the seller who is breeding high end kamfa’s for competition and he says nothing is wrong. But that I should keep an eye on it, and that I potentially could use Japanese yellow medicine that is usually used to treat gold fish and koi. I have searched on the forum and online and I have not found an answer as to what it is. The fading pictures I’ve found usually shows the entire fish getting dark when it is fading. I wonder if it’s an issue with the enhancer food? And the pigments in the skin? However this is only an assumption. Nitrite/nitrate is 0 same for ammonia ph is around 7.6. Any information, suggestion or general idea as to what caused it or what it is would be greatly appreciated!
