Domino Damsel compatibility?

You should have gotten the domino last. They are extremely territorial and one of the most aggressive damsels. If you add anything, it will kill it. I would suggest returning the damsel, or since your moms in love with it, settin up a temporary tank for it, then rearrange the rocks a little then add the blenny. Depending on the clownfish you get, you will either have to add the clown first and then the domino or add them at the same time. FYI, maroon clowns are the most aggressive so if you got one of those, you'd have to add it in with the damsel at the same time. Just do research on the type of clown you want first. Occelaris and perculas are the most peaceful. Hope that helped

I have a Domino that is in a 120 gallon with 2 blue damsels, 1 velvet damsels, 2 Clarki clowns and 2 snowflake eels. The clowns are bigger than him so he doesn't bother them at all. He does seem more aggressive than the other damsels though. He is pretty good at stealing the eels food during their feeding times. As you can imagine this makes them very angry. One of these days they might just make him their meal.
