Bisma Worm Rock (Porites)
Porites Coral Care
Porites are a Genus of small polyp stony corals (SPS) that are somewhat uncommon to the reef aquarium hobby. Most of the time they grow finger-like structures from a massive encrusting base and come in a variety of colors. Porites are rarely known by their common name “jewel coral.” For some corals, their scientific name tends to stick. Please see below for additional care tips for Porites as well as checking out our Top 5 Tips for setting up a reef.

Porites are commonly found in very shallow water and enjoy intense lighting. Use either Metal Halide lighting or a large bank of high output fluorescent or full-spectrum LED's. We keep ours in about 200-PAR however it is not out of the realm of possibility that the shallow water varieties receive over 1000-PAR.Low Light
Low light translates to about 30-50 PAR
Medium Light is between 50-150 PAR
High Light is anything over 150 PAR
Lighting is a loaded topic, so for a more in-depth discussion of lighting, please see our Deep Dive article.
Strong water movement is recommended. Porites grow in some of the heaviest flow areas on the reef.
Porites are not well known for their appetite however large colonies frequently house Christmas tree worms that are beautiful filter feeders. Regular addition of phytoplankton and smaller zooplankton may be beneficial to both these worms and the coral.
This genus for the most part has been propagated extensively in captivity and is an excellent candidate for aquaculture.
Proper acclimation is extremely important considering the stress imposed on the animals by the shipping process. Please take a moment to review our Acclimation Guide.
The images were taken with a Canon 5D mk II and 100mm macro lens under T5 Fluorescent lighting. Quite a lot goes into how we go about shooting the corals and anemones you see on Tidal Gardens. For an in-depth look at our methods, check out our comprehensive Reef Aquarium Photography FAQ.
