walked by the tank while the moonlights were on this morning and i see my moorish idol all beat up and missing a bunch of his fins.
looks like he got beat up.
the most recent fish i added was the black shoulder tang and for 2 weeks now he seemed to fit in just fine. no aggression towards anything.
i moved the idol to my refugium but i dont know if its gonna make it
anyone know why fish suddenly snap and become aggressive?
