LPS, or Large Polyp Stoney, is a hobbyist term used to describe certain types of coral.These corals generally have very large, distinct fleshy polyp(s) over a hard calcareous skeleton.All kinds of corals are included in the group, from brains to chalices, Hydnophora to Caulastrea.Obviously this variety will also lead to a certain amount of variability in care and optimal conditions.However, there are some basic general guidelines that may be applied to most members of the group and will aid in their care.
Generally easy to moderate
Most moderate to highly aggressive.Many LPS have potent stings and may produce sweeper tentacles to deliver that sting to their neighbors.
Moderate lighting is generally preferred.
Moderate flow.These corals often have large fleshy polyps and sharp skeletons.Excessive flow can cause tearing.
Low to Mid tank
Many LPS corals are fairly tolerant of slightly dirty water.Maintain good Alkalinity, Calcium, and Magnesium for skeletal growth.
Many LPS corals have large obvious mouths, and will accept meaty foods like mysis shrimp.For some, this feeding is an optional supplement while other species are unable to sustain themselves long-term solely on the products of photosynthesis and will gradually waste away if not fed.
For especially fleshy LPS, be sure to allow the coral to close before removing from water to prevent damage to the tissue.
