Let's see he has a 80gal tank with a show size Clown Trigger, say about 8"-10" and Queen Trigger that about 6" a large Volitan Lion a Purple tang and a Semi-Lavartus all in an 80gal tank with rock in.
First off the Queen trigger will get about 2' when full grown, and since he has the fish for a while and it's only 6" or so there seems to be a problem there. Also large Queen Triggers as very aggressive and usually attack almost everything in the tank. Not to mention a Very Large Clown trigger in the same tank. And to top if off a Semi-Lavartus butterfly.
