Purple People Eaters are similar to other Colony Polyps in that they are relatively easy to care for and can be successfully housed in a variety of reef aquarium setups. They require medium to strong lighting and moderate to strong water flow in order to allow their symbiotic algae zooxanthellae to thrive and produce food for the coral. While most People Eater Zoanthid morphs acquire the majority of their nutrition from photosynthesis and do not require supplemental feeding. Some individuals have acquired higher growth rates through supplemental feeding of very fine foods intended for filter feeding invertebrates. The addition of reef additives like: calcium, strontium, iodine and trace elements along with occasional feedings of micro-plankton and similar foodstuffs should allow for the best possible growth rate. Purple People Eaters Zoanthids kept under proper aquarium conditions will spread or colonize nearby rocks and hard surfaces. In order to keep them separated from other coral species the hobbyist should provide gaps between the rock aqua-scaping, in order to create a boundary to limit the carpeting or horizontal growth of the Polyps. Proper placement is important when keeping Polyps with other corals, as Polyps will crowd out other corals by stinging them repeatedly as they grown in and around them. Hobbyists are recommended to start their PPE Zoas in a lower position on the reef and move them up the reef after they have had a chance to acclimate to the aquarium.
Purple People Eaters Colony Polyps receive the vast majority of their nutrition through the symbiotic algae zooxanthellae contained within the coral. They receive other nutrients from dissolved minerals that they filter from the water currents. They will also benefit from the addition of reef supplements containing calcium, magnesium, iodine and trace elements. They can also be periodically offered meaty foods like micro-plankton, baby brine shrimp and other similar fare.
