Euphyllia glabrescens, or torch coral, is a large polyp stony coral that has long been a classic in the aquarium hobby. It’s related to the even more popular hammer and frogspawn corals, which are members of the same genus and similar in appearance: elongated polyps with a colorful tip.
Naturally found in tropical areas of the Pacific Ocean, torch coral can be found in a range of colors. It’s a decorative addition to the aquarium because of the way its polyps sway in the water flow. The tips of their tentacles almost appear to glow under the right lighting.
