Get peppermint shrimp. Natural way of removal is better to keep it under control. As some hide in rockscape that we unable to see.

Dottyback is known to fight its own kind. But if you have enough real estate they should be fine. By that I mean really alot of holes in your rockscape. But it depends on luck sometimes. Just like placing hammer next to torch coral. It can be fine till one fine day they start a chemical warfare.

Looks good. Would love to get some after I release my tomato clown. Preferably a pair.

How big is your tank in the first place? Every tank is different and there is no replicated parameters or dosage for every tank

Just keep vaccum them out and they goes away with frequent water changes.
