I have recently obtained a 29 gal Bio Cube and have set it up with live rock and a couple turbo snails. After I placed some new live rock I noticed Aiptasia Anenome's. I wanted to get Burghia nudi's but couldn't afford so I bought a Peppermint shrimp which ate my Kenya Tree and not the Aiptasia. So my question is 1.) how to get rid of Aiptasia naturally without losing soft corals? and 2.) is the Peppermint compatible with anything? I am wanting mostly corals and invertabrates in my tank for now. Thanx!
