NPS (Non-photosynthetic Corals)

Non-photosynthetic corals do not contain zooxanthellae in its tissue, thus having to derive all of its nutrition from organic matter.

Since they do not require sunlight for growth, these corals are normally found inside and along cave walls and overhangs. In the aquarium, this coral requires feedings of meaty foods such as brine shrimp and mysis shrimp at a frequency of 2-3x a week.

NPS corals are considered difficult to care for due to requirement of frequent feedings. They generally will feed at night but can be easily trained to stay open pretty much all day depending on when you feed them.
