Hi all, hoping you can help me with my two clownfish. I got them about 6 weeks ago as the first two fish in my tank. I got the tank from someone who had the tank up and running for years. About 3 weeks ago, the darker clown started showing signs of white stuff on his lips. I thought it was from him biting something or bonding with the other clown, but it seems that is not the case as the white has gotten worse and is now on the lower end of his gill plate. It also seems to have spread to the orange clown as well, showing up slightly on his gill plate. Both fish have been eating (very!) well, fed a mix of various frozen food(marine cuisine variety pack) and PE pellets. I have no stinging corals in the tank. Some of my hermits have been dying, but i think that’s due to a predatory nassarius(or maybe not nassarius?!?) snail so that’s a different story.
Parameters are good and steady with 0/0/0 ammonia/nitrite/nitrate, 8.2 Ph and 1.025 salinity. Tank at 75/76°
What do you think they have? I’m not incredibly concerned as they have been eating well, but it’s clear that they have something as it’s grown and spread to the other clown. I’m worried that the growth on her(?) lip may prevent her from eating eventually. Thanks in advance for the help! I’d appreciate any treatment advice you have as well.
