Interesting reading! I just started a marine tank and one of the guys at my lfs
told me I could put a 3-spot Damsel, a Yellow-Tail Damsel, and a 4-Stripe Damsel together in the tank! What a load of crap that was. The first Damsel to bite the dust was the 4-Strip. He did not even last a week. The next one to go was the Yellow-Tail Damsel. He lasted a month. Now all that's left in the tank (while it cycles) is the 3-Spot. I plan on adding Chromis' next and if he starts to annilhilate them, he's going to become cat treat!
