Comb Coral, Tooth or Wonder Coral (Catalaphyllia plicata)
This Comb coral as I call it, has only been in my tank for a couple of weeks. But in the time it has been within my tank has progressively expanded further and further. Again under the actinic light, this coral flouress brilliant greens. The coral receives a good amount of continuos flow and also gets a blast every minute from my main filter.
