Our corals are photographed under a combination ATI Blue Plus T5 bulbs and Reef Brite XHO Blue LEDs. The corals will look different under different lighting combinations. We find this light combination is what promotes the best balance of coral coloration and growth.
These like low to medium light with low to medium flow. Generally you do not have to feed them and they do well with good lighting and dissolved nutrients. Hammer Corals, Frogspawns, and Torch coral are all in the Euphyllia family and have the same requirements. You can often place them close to each other to make a nice garden of different colors and textures.
