The Yellow Colony Polyp Corals are colonial animals with several individual polyps attached to a piece of live rock or coral rubble. They are bright yellow in color and their polyps have the ability to sting other polyps or corals. While the sting is not strong, they are semi-aggressive and need to have space between their colony and any neighbors.
Easy to maintain, the Colony Polyp Corals require a medium light level combined with a medium water movement within the aquarium. For continued good health, they will also require the addition of iodine and other trace elements to the water.
They will reproduce easily in the reef aquarium by budding (splitting off a portion of their base or mouth), which will increase the size of their colony.
They contain the symbiotic algae zooxanthellae which provide some of their nutritional requirements. They must also have additional feedings of micro-plankton or brine shrimp given to each individual of the colony. (liveaquaria)
These were the first types of polyps introduced into my tank. For the picture, I had a pinpoint light source behind the aquarium pointing downward so that the polyps were backlit.
