Purple Rimmed Cap Coral: Montipora capricornis

Phylum: Class: Order: Family: Genus: Species:
Cnidaria Anthozoa Scleractinia Acroporidae Montipora M. capricornis

Common Names:  Purple Rimmed Cap, Purple Rimmed Leaf Plate Montipora

Scientific Name:   Montipora capricornis

Purple Rimmed Cap grows in upwards facing whorls or outwards facing plates with multiple tiers.  They may also encrust onto nearby surfaces.  The surface of the coral is bumpy with inconspicuous polyps.  Color is a uniform light to medium green color with a contrasting purple edge.

Natural Environment:
Lagoons and similar environments.

Purple Rimmed Cap coral is one of the hardier SPS corals and can usually adapt to sub-optimum conditions.

Moderate to intense lighting.  Coloration tends to be more intense under higher lighting intensity.

Water Current:
Moderate to fairly strong water current.

Low.  If the Purple Rimmed Cap comes into direct contact with another SPS coral, it will tend to be the loser.  These battles limit the growth of the coral in those areas and may cause some die-back, but it will not cause significant harm the coral.

The Purple Rimmed Cap is photosynthetic and require no direct feeding.  It is unknown whether they will take any offered foods.

Supplements & Water Chemistry:
Salinity should be maintained between sg 1.024 and 1.026.
Alkalinity should be maintained in the dKH 7-12 range
Calcium should be maintained at 400 ppm or higher.
pH should be maintained between 8.1-8.4

Does well within a range of at least 74º to 84º F

Tank Positioning:
Best positioning is in moderate to fairly strong but not laminar water flow, in a moderate to bright light area of the tank placed placed so that the coral can grow out horizontally unencumbered.  It has a fairly weak skeleton and is best positioned where it won’t get bumped during tank cleaning.  Also keep in mind that as the coral grows and the plates extend out, they will shade whatever is below them.

The large plates are susceptable to catching debris on the top or bubbles on the bottom which can cause small areas of die-off if not removed.

The branches of the coral can be broken or cut into small fragments and glued flat (usually) or on a cut edge to a suitable substrate.
