Hammer Coral

This coral receives most of its energy by utilizing the photosynthetic algae contained within its tissues. It can also absorb dissolved nutrients from the water and may be offered zooplankton coral preparations, rotifers, mysis shrimp, enriched brine shrimp, oyster eggs, etc.

Although Euphyllia corals can be quite hardy and not prone to pests, they are not tolerant of poor water quality and may fail to extend their polyps. Physical damage to the coral should be avoided at all cost, as it is prone to infectious brown jelly infection.

This coral should be provided with plenty of space as it may produce long, powerful sweeper tentacles; low water flow helps to minimize the growth of these tentacles.

Emerging from a single, undulating skeleton are countless waving polyps, each with a uniquely shaped tip that resembles a ship’s anchor.

Many color combinations are possible, with Australian corals being more rare and impressive than those from other locations.

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.
