My scopas started acting strange today. I can’t tell if this is scratching, flashing or any typical territorial tang behavior. He is very small. I have had him and 2 clowns for about 3 weeks. All fish quarantined at LFS for 4 weeks. I don’t see any white spots or rapid breathing. There is possibly one tiny black spot on him but can’t tell if it is anything or just part of his markings. Very friendly with clowns and no nipping. Eating normal too. Any thoughts or ideas?
