Tomato Clowns and Domino Damsels

Sorry to tell ya but no, Tomatoes are one of the larger and most aggressive Clowns available and since Damsels and Clowns are in the same family it will be WW3 until both the Damsels are killed. I would go with a pair then maybe do a small wrasse like a 6 line or some gobies. Anyway, hope this helps and good luck.

Please listen to Mono I foolishly placed a tomato clown in my reef community tank. He was quite please with the arangement cause there were all those nice critters in there for him to eat one bite at a time. At the time I was relying almost 100% on the advise of my lfs and they kept telling me oh no can't be your clown must be something on a piece of your lr. It went on about a week till Icaught him in the act. Yes, I was alway suspicious about him I'd seen him chase the other fish but, not use those pearly whites. She is now the single inhabitant of 20 gallon set up and doing well. I might add some sessile inverst later on but... with these fish err on the side of caution. Course I might have had a psychotic fish but I really don't think so.
Warm regards
