The aipstasia is a super cheap (read: free) alternative to corals. They attach immediately, so I never really have to put my hands in the tank to straighten frags that get knocked over and risk getting smacked in the fingers. Also, it cuts back on mixing new water since I use old water from my larger nano reef when changing water in this tank. Aipstasia is a great natural filter.
I've had my mantis for about 7 weeks, so maybe it isn't quite at home yet.
Let's see some pics of your set-up, Molino. (Aw, I just saw a pic on RC.com. Ha ha.)
