CB Snitches Zoas
In terms of care, both Zoanthids and Palythoa are fairly easy to keep. They tolerate a wide range of lighting intensities and water conditions. Once settled in, zoas multiply quickly. Zoanthids are unique due to how they incorporate sand and other small pieces of material into their tissue to help create their structure. In the wild, Zoanthids often occupy fringe environments (intertidal, back reef, other shallow areas, over dead corals), making them quite a hardy choice for the reef aquarist.
For continued good health, they will also require the addition of iodine and other trace elements to the water. Zoas 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 will also benefit from additional feedings of micro-plankton or brine shrimp given to each individual of the colony.
Waterflow & Lighting
Zoanthids require moderate water flow and low to moderate lighting (PAR 100-250) to maintain their color. T5’s, Metal Halides, or LED’s can all grow Zoanthids and Palythoa when the proper PAR levels are provided.
Zoanthids and Palythoa are found in corals reefs around the world. These polyps are harvested mainly from the islands of the Indopacific including Fiji, Tonga, Solomon Islands, and the Great Barrier Reef. Zoanthids and Palythoa have an incredible array of colors and patterns that make them one of the most popular corals in the reef aquarium hobby.
Some Zoanthids and Palythoa contain a powerful neurotoxin called palytoxin in its flesh that can be extremely harmful if it comes in contact with your blood stream. By harmful we mean deadly. Take special care handling these polyps for this reason especially if you have open cuts on your hands.
