An amazing lps! The Dendro is very much like the common sun polyps (aka Orange Tubastrea) but the difference is wonderful. Unlike Sun Polyps, Dendros stay open during the day if you feed them during daylight hours. They only need to be fed once or twice a week and each head reaches a mature size of over one inch. The contrasting color of the mouth is stricking. Best placement for a Dendro is on the sand bed in low light and moderate flow.
