Faviidae, or Closed Brain corals, are quite hardy and adaptable, making them a great first introduction to stony corals. Their wide array of possible color combinations make them popular with experienced reef-keepers as well. They are tolerant of less-than-perfect water quality and are not prone to pests.This coral receives most of its energy by utilizing the photosynthetic algae contained within its tissues. It can also be offered zooplankton coral preparations, rotifers, enriched brine shrimp, oyster eggs, etc. Its transparent feeding tentacles extend mainly at night, although it can learn to feed during daylight hours. Colonies with very bright colors and flat forms thrive under bright light and strong water flow; rounded, dome shapes need moderate light and flow.Some species are able to produce copious amounts of clear mucus and should be rinsed well before adding to a display aquarium. Space should be provided between corals to allow for growth and expansion, as its long sweeper tentacles have a strong sting.Leptastrea is a beautiful stony coral with small, tightly packed polyps. It is also known as crater coral, however when its polyps extend it takes on a fuzzy appearance. Australian specimens are brilliantly colored and strongly fluorescent under actinic lighting. All this combines into a striking display under any lighting conditions.This coral receives most of its energy by utilizing the photosynthetic algae contained within its tissues. It can be offered powdered or liquid zooplankton coral preparations, and it can also absorb dissolved nutrients from the water. It is sensitive to fluctuating alkalinity levels, but otherwise makes a very hardy addition.Water flow is best provided as turbulent flow with the use of a wave maker or surge action. Constant laminar flow is very damaging and could cause death of the coral. Alkalinity, calcium, magnesium and strontium are required for growth and should be checked regularly.
