Kole tang is being an A-----E

[Reef Pilot]

Yup, a tang is a tang... I have 2 Kole tangs, one in each tank,... great algae eaters. But like most tangs will harass new fish if they see them as a threat or competitor for food. Good news, is the Kole's are not as bad as the yellow or purple tangs (have one of each of them, too). And after a few days, the aggression should subside and most likely will leave your Flame Angel alone completely in a couple weeks. The picture or mirror on the glass trick helps, though, to distract him if he is really bad (had to use that with my yellow tang many times).
