My royal gramma is in my tank with a pair of clowns. Early this week it looked as if had a bite mark or a lesion. Now it has grown and developed a hole right through his body. How should I treat this when I try to catch him to put him in my QT.
Either way the fish should be treated with both anti fungal and parasite meds in the qt. It could be a wound but the fish is susceptible to disease now.
