I know general rule is that corals can touch their own species without any stinging issues, but since there’s different “subspecies” of Acropora, do they need to be separated from eachother? I currently only have 3 different Acros in my tank, but each one is a different species, a Millepora, a Tenuis, and a Valida, and they’re all in their own designated area high in the tank currently, but I’m wondering if I’ll run into any issues and need to relocate them as they grow.
