Not sure what this is, only affecting one of the clownfishes, parameters in line, picture also there. Salinity at 1.026.
They are all eating normal, only 2 clownfish and 1 starry blenny (Which is hard to see if has any spot because well, starry blenny and hides until feeding time)
Any help is appreciated. Tank running for almost 2 months, cycled for 1 month. QT tank or hospital is not possible unfortunately so any treatment would have to be at DT tank.
Thank you!
