I just added a Chevron tang into my tank last week. I have had this Chevron in my sump for a few months, eating well from a Nori clip and frozen and flake food. I got him from a friend who wanted to added a more expensive fish t his tank and afraid that the Chevron will harassed it.
Any predictable, the Chevron tang, the largest tang in the tank at this time, was bother and driven to the rock by my other tangs. I have to put a food clip on a stick to where he is hiding and he have been eating well even if he is in hiding fro the other tangs. I think in a few weeks, he will venture out and be a normal tank citizen.
No significant injury, just a few scratches on the body and several split in his fins. Witj a;; the food he can eat, and he have been eating a lot, I think he will be fine in a few months
