Where did you get your mantis from? Does it not knock over ur frags aswell?You can spend a week at my place. I have 5 aquariums. 2 are SPS dominated tanks. 1 is a skunk clownfish mom/dad anemome tank, 1 is the clownfish baby lagoon with RBTA's, and the 5th is an Acro Dominated mantis tank. It houses a pseudosquilla ciliata.
