I discovered a small breakout of Aiptasia and a couple of Mojavo Anemones on a piece of live rock I recently bought and today I purchased three Peppermint Shrimp to solve the problem. However, I also have 2 small corals I am growing (a blue spotted mushroom and some sort of finger coral I have yet to be able to identify). As soon as they hit the tank the shrimp wiped out the Aiptasia, but one of them also made an advance at my finger coral. It has since left it alone, but is this something I should be worried about? I would like to keep the shrimp in the tank in order to control pests, but I do not want to do this at the expense of my corals. Any advice would be much appreciated.

What is a good figure for tank turnover for a reef + fish, my LFS said that 17 times was too much for my 55G but i don’t want to go to the expense of a new pump so i am using the one i used to have set up on my 90G.
