These are asexual animals that will reproduce by budding. They form daughter polyps that fall off and grow near the mother polyp. They will multiply fairly quickly in good water conditions, and require one feeding a day to maintain good reproduction. You may feed them a number of different foods that include crushed tablet food, Daphnia, Cyclops, mussel flesh, and a number of invert feeding supplements that are commercially available. They need to be fed directly into the feeding tube to prevent fouling of the tank.
Yellow polyps tend to be hardy as long as they are fed, and have proper lighting.
They're compatible with most reef fish, although they should not be kept in the presence of some wrasses, and larger angels, which tend to eat the tentacles of the polyp. So as long as the reef keeper is experienced with feeding corals and anemones, keeping this animal should not be difficult. Colonial Anemones in general do very well in maintained natural systems. Plankton in the tank are invaluable to the health of the animal, and specialized supplements should be provided on occasion.
