Nice!!!! This trigger is Melichthys family, I think! (if not someone correct me please ....lol), it would be from the same family as the pinktail which I keep with my lions. No problems with my combo but it will depend on the trigger.
Feed a variety of meaty foods and greens soaked in vitamins a few times per week, I feed my trigger Nori, Fresh Frozen Peas (Thawed) & Fresh Frozen Broccoli (Thawed) which your Tang will also eat. The meaty foods and greens are very important in your triggers diet, I have fed my Pinktail this way for the past few years.
Two of my Volitans & fuzzy eat Peas but I have avoided the Broccoli with lions, I did not want them eating peas but they like them....
Beautiful fish......
