advice on a couple of fish i'm thinking of getting

[fishshark30]

I am new to going on threads but with my years of experience with Saltwater fish, Triggers is kind of bad, especially when I seen them eat other fish and tear them apart, it really made me mad. I feed them plenty too and it still decided to eat like it was an all you can eat buffet. As for butterfly fishes, it states in some that butterfly fishes is coral polyp eaters and they are not safe for any reef tank, yes I do have 2 pebbled and a coricola butterfly fishes and they ate my coral up and It hurts when you spend money so I was disappointed, but after adding new corals, I got them to eat flakes instead, so now they tend to be waiting for breakfast or dinner time so it ain't all that bad. Anyways, I hope you do well with your decision. Good luck.
