I am developing an aptasia problem. Tried peppermint shrimp, but cleaner shrimp killed them right away. Got a long nose butterfly, as recommended by guy in fish store, but i have been reading and am not sure I should have in my reef tank, and it has been in the tank for 3 days and hasn't moved out of the corner, so it looks like that isn't going to work. What are the consequences of the aptasia spreading and does anyone have another idea for me to get rid of them.
