Hydnophora coral is one of the SPS corals that is sometimes confused with Acropora.

Color is usually a shade of green from yellow/green to bright neon green.

Hydnophora is generally more tolerant of tank conditions than Acropora, though it still requires good lighting and water movement.

Hydnophora is perhaps the most aggressive of all SPS corals and so some space should be left around it to prevent confrontations with nearby corals.  2″ of space around it is usually enough to avoid trouble.  It can be a fairly fast grower, so best to plan ahead and leave it plenty of room.

As is the case with all stony corals, attention needs to be paid to maintaining proper Calcium and Alkalinity levels in the reef tank for proper skeletal development as noted on the right.

Photo Notes We want you to be happy with the coral that you receive and we take pride in the corals that we offer.  To provide true representation of the color and health for our WYSIWYG corals, they are photographed and white balanced under the ReefCorner LED lighting at approximately a 10K to 14K white point to best show the actual color of the coral. The coloration may vary when viewed under different lighting.  The grid the coral is typically photographed on is approximately 0.6" per square to give you a size reference.
Naming Notes We identify the scientific name when we are able to with some degree of accuracy. You will notice that we don’t give our corals cool names like “AWESOME ULTRA SUPER METALLIC NEON RED AND SCREAMING LIME GREEN ULTRA ULTRA COLORED AUSSIE” unless it is a name in common usage in the hobby that helps to identify the coral. We let our pictures do the talking and you can be the judge of whether our corals are awesome or not.
