I have seen those cysts on the fish near head and tail fin and they have already fallen off, now the fish seems to have a bigger marks on his head, for lack of a better way to explain... Its kind of like velvet, if u brush it one way its a dark color if u brush the opposite way its a whiter, lighter color. This is what his head is starting to look like. Its a coral beauty so hes a dark purplish, so it kinda looks just like the velvet example. Maybe what Im seeing is the mucus they secrete im not sure. Ive tried to get pics but the fish is very active its a pain ill try again tonight. Thanks for the response
