Native Habitat and Species Information

Yellow Colony Polyp native habitat, distribution, behavior & aquarium compatibility.

Yellow Colony Polyps are an attractive and easy to maintain Parazoanthus species best known for their distinctive yellow coloration and long tentacles. Their hardy nature and modest lighting and water flow requirements make them ideal for beginning reef aquarium hobbyists. In fact most hobbyists find that the trick to caring for Yellow Colony Polyps is to restrain them from over growing the entire aquarium.

It is recommended that they be isolated on a piece of rock or coral rubble separate from the main reef in order to keep them from spreading out of control. To allow the Yellow Colony Polyp to spread onto the reef, the hobbyist need simply place the rock containing the Polyps next to a bare rock and they will quickly begin colonizing the new real estate.

Aquarium Care

How to successfully keep Yellow Colony Polyp in the home aquarium.

Yellow Colony Polyps require only moderate lighting and water flow in order to grow and thrive. They should be kept in an establish aquarium with clean water and stable water parameters. They can be placed at any level within the aquarium as long as they have rocks or coral rubble to attach themselves.

They do not require extremely bright lighting, but they should be provided a proper marine reef aquarium light spectrum ranging from 10,000K to 20,000k daylight and actinic blue lighting. Power compact fluorescent, T-type fluorescent and LED style lighting designed for marine aquariums should be more than sufficient for the Yellow Colony Polyp to support the symbiotic algae zooxanthellae hosted on its body.

Yellow Colony Polyps are peaceful species that should not pose any danger to other nearby coral species. Yellow Colony Polyps is heavily predated by fish species that eat corals, thus should not be kept with fish species that are known for eating or picking at corals.

Feeding & Nutrition

How to feed and provide proper nutrition for Yellow Colony Polyp.

Yellow Colony Polyps are photosynthetic and receive the bulk of their nutrition from the symbiotic algae zooxanthellae which it hosts. While supplemental feedings are not required, they will increase the growth rate of the colony. Weekly feedings of brine shrimp, mysis shrimp, cyclop-eeze or other similar meaty foods with greatly accelerate the growth of the Yellow Colony Polyp colonies.
