So I have a birdsnest and a fire digitata which both seem to be healthy, Im wondering about adding another birdsnest and putting it next to the current one and watching them intertwine so different colors. Good or bad idea? The other question I have is what would be another good beginner SPS coral that I can add to tank and not worry about putting it next to others. Running out of room with my recent anemone split(probably need to get rid of one of them)
