Common Names: Purple Goniopora Coral, Purple Flower Pot Coral
Scientific Name: Goniopora spp.
An encrusting roundish to oblong flattened colonies with long purple polyps that sometimes have a yellow or creme colored center. Each polyp has 24 tentacles and can extend to 3″-6″. A similar species Alveopora is sometime confused with Goniopora, but it can be differentiated by the fact that it has 12 tentacles.
Typically found in low to moderate current areas such as lagoons. Sometimes associated with turbid water conditions.
Goniopora is considered to be delicate, though the purple variety is hardier than the more common green variety. Not recommended for the beginning hobbyist.
Prefers moderate to fairly bright lighting. The specimen on this page was kept 24″ under 400W 10K Metal Halide lights.
Prefers moderate water motion that keeps their polyps gently waving in the water current.
Appears to be low. While they have a long reach, I have not observed them fighting with their neighbors.
Goniopora is primarily photosynthetic though some hobbyists have claimed success with feeding their specimens using very small food such as frozen rotifers, golden pearls or cyclopeeze. There has also been some anecdotal evidence that they may generally prosper better in tanks without strong protein skimming due to the higher levels of detritus in the water which might more closely match the turbid waters that they are found in naturally. The method of death when a specimen dies is usually a long period of decline that may be caused by nutritional deficiency.
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
There has been debate whether iron, manganese or other trace elements may be important to their health, but there has been no hard evidence presented so far.
Does well within a range of at least 74º to 84º F
Best positioning is in moderate water flow, in a moderate to fairly high light area of the tank placed either on rocks where it won’t fall or placed on the sand bed.
There have been some successes reported using a band saw or other techniques to carefully fragment a colony. The broken skeleton is usually glued to a plug to keep it from floating away. Captive bred specimens are sometimes offered for sale.
