Please does anyone have someDamsel advice

[Bob I]

The story is this; In my soon to be 50 gallon Fowlr (36x18x18) I wanted some inexpensive colour. Reading "The Marine Aquarist Survival Manual"
convinced me that Yellow Tail Damsels should be kept in odd numbers such as three, and should not be kept singly. So with some trepidation I picked up three. To make a long story short, the Damsel wars soon started. One was attacked consistently, and had very few hours to go before he was killed. I took pity on this beast and put him into my 20 gallon Mini Reef. He revived soon, but of course the Royal Grama does not like him either. At least it is not all out war.
The real question is this; How do Chromis get along with other Damsels? Would the addition of three Chromis to the tank with the remaining two YT Damsels cause problems? :x :?
