Thanks everyone for the info.
sphelps I love your Fu manchu! The thought of a seahorse ridding around on him is awsome
I really like the looks of a fu manchu and my lfs is supposed to be getting one in soon, but I'm not sure I should get one. I started thinking about it when I was talking with some employees at a lfs about my really mean King angel, and I was telling them that between my king angel and my large grouper that I wouldn't be able to add anymore fish to that tank. My king attacks anyone that is remotely similar to her and the kind of fish (large wrasses and groupers) that she would leave alone, my miniatus grouper wouldn't aprove of. So the guy said why don't you get a lionfish, most fish know to leave them alone, and that got me thinking.....
I don't want to add one though if there is any chance that my king or grouper would hurt it.
