the only potential problem i see may be your Diadem Dottyback. These fish are notoriously aggressive towards other small fish and would likely cause problems with your damsels, clowns, and even the blue tang, other than that just be cautious mixing a single 3 stripe, (humbug), with peaceful fish, it's possible he could get aggressive as well.

I've already got the diadem. He is the most passive fish i have ever seen. He never bothers anything. He is just very curious and likes to know what is going on
