I bought a small rock with two types of zoas and some other coral on it. Id like to remove the zoas and put them on a frag plug to seperate them and also dont want the rock in my tank any longer since I don't want the coraline algae taking over. On videos people show methods of using a wood chisel with large colonies that have mats but what could I use with a colony this small? I dont have any wood chisels that small either.
