I recently bought a frag rock with 10 frag plug holes. Right now I have blasto’s in 4 of the holes to make a garden. My question is, are there any corals out there that I could place on the other side of the rock (6 frags) that would not cause an issue with coral warfare in 1 or 2 years when they grow into the blasto’s? Any ideas/suggestions would be greatly appreciated As I’m not sure what could be placed/touching blastos with no ill effects. TIA!
