When you manage to keep SPS healthy and growing there is nothing to worry about.Nice idea, never seen someone do this before. Also how does your Auriga butterfly get on with the sps and other corals you’ve got? It’s one of my dream fish but I’ve never pulled the trigger on one, I always thought it would destroy my corals.
I would not trust them (yet) with lobos, blastos, acans, zoanthids. Who knows i will experiment with it later on, when i have some for spare.
It is a great pest remover aptasia, majano, t-asters are getting cleaned out thoroughly.
