I recently added a tailspot blenny. He was very active at the fish store and showed no signs of illness or discoloration. I don’t have a QT system although I know I should. I know blennies can get white spots or lines when stressed or at night but mine only has a couple of white spots on it’s face. Could this be ick or some other disease? One side of the blenny is completely fine while the other has a few white spots on its face and side. He never competed for food but he still eats when it floats to his section of the tank. If anyone could let me know if my fish is sick and suggest a treatment I’d greatly appreciate it!! Here are a few pics
