Yellow Polyp Corals are colonial anemones rather than being a type of coral.  Science has struggled with defining their genus classification, but Parazoanthus seems to be the most common classification.  Being colonial animals each polyp is an individual animal.  They come in various shades of yellow from cinnamon to bright yellow.

They are very hardy animals and easy to maintain if given moderate lighting and water flow and therefore are a good corals for beginners.

They are photosynthetic, but their long-term health may depend on receiving at least occasional feedings of small meaty foods or filter feeder foods.  It is possible that feeding is only required if they are maintained in low light conditions.  There is much disagreement about this in the literature.  We feed our tanks small meaty foods such as frozen Cyclopeeze 1-2 times a week, but it is unknown if the yellow polyps benefit from that.

Yellow polyps can be somewhat invasive as they will reproduce by budding and so an eye should be kept on them to make sure they aren’t encroaching on neighbors.  Isolating to a rock island on the sand can keep them contained.

Yellow polyps are also a favorite food of some types of fish such as Anglefish or Copperband Butterflyfish or filefish used for Aiptasia control, so care should be  used in tanks that contain those types of fish.

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.
