Hi, I think that the bubble coral is somewhat related to frogspawn/hammers, but how close can they be to each other? Can the bubble coral be only a few inches below the frogspawn? Am I correct that bubble corals dont need or like much light? I am trying to rearrange my tank for a lta(long tentacle anemone) and want to give the lta plenty of room to grow and not hurt the other corals. THANK YOU.
