I was sitting in front of my tank trying to come up with an idea to cover a rock wit a specific coral. I thought about doing maybe a cyphastrea rock but I heard that 2 different colonies would fight. Then I thought about a zoa rock but I figured i would let them grow wherever I found space for them. Finally I thought about doing a blastomussa rock. Would I be able to mix wellsi's and merletti's on the same rock without fighting? Or even 2 different colors of one type? Please give me advice on this.
