Just wondering, but has anyone ever seen their yellow tang pick at another fish's tail or fins? He is doing it to my brand new Miniatus Grouper (beautiful fish) and now his tail fin has a small split in it and it has some fraying. His top real fin has an uneven edge now and the bottom fin did have a split but it has already healed in the past few days. The weird thing is this big grouper is letting a tang do this to him. My water levels are normal and I dont believe it is fin rot because one of my fish had it before and all their fins start to look bad. Also the groupers side fins look great, not one spot, and the other fins look perfect except for what small spots I mentioned. I just want to know if there is a way to stop the tang from doing this? I dont want this beautiful fish distroyed by a tang. Will the fins heal without medicine? Can this make the grouper sick or die? I try to avoid medicine at all costs now because it destroyed my biofilter and caused me to have to let the tang cycle again with the fish in it. Very stressful. Thanks for any info.
