Hello, So i recently just got a new scopas tang ive had him in my tank for about exactly 1 whole day now and i’ve closely noticed that he flinches or twitches his top fin every so often (i’ll insert a video below) he’s house in a 120 gallon with just one small foxface. I had 4 clowns in my tank who came down with brooklynella yesterday right after i put my scopas in the tank after acclimated. Anybody know what the twitch could possibly be?
