Rainbow Wellsophyllia is WYSIWYG, approximately 4″ in length. This wellso is a show-stopper! Feed this LPS coral DAILY, provide enough gentle water movement to keep it free of detritus, slowly acclimate it to stronger lighting, keep calcium levels up and place in the substrate. When lifting it out of the water, make sure it is fully deflated and try to keep it submerged when transferring since the skeleton can easily tear the tissue under its own weight.
The Wellsophyllia genus, like other large polyp stony (LPS) corals, have developed several feeding strategies. Through a symbiotic relationship with a marine algae, known as zooxanthellae, they receive some of their nutrients. They also capture planktonic organisms, food particles from the water column, and can absorb dissolved organic matter. Feed it daily. They will eat mysis, fortified brine shrimp, rotifers, Cyclopeeze and other similarly sized meaty foods. Larger pieces than a typical mysis is not digestible, and although the animal “accepts” it, it will regurgitate it up later in the night. So use smaller foods or your coral can waste away in a little over a year. Typical water changes of 20% a month, 10% biweekly, or 5% weekly are needed. It has been noted that 5% weekly water changes replenish many of the needed additives and it is ultimately cheaper than purchasing additives for the water.
