The Leather Coral are a unique soft coral. They are some of sought after and the most attractive corals found in the world's oceans today. They tend to be soft and very flexible, but they also have a "leathery" feel to them.

As Leather Corals do not have a calcified skeleton structure, they can be more tolerant of swings in the calcium, magnesium, and alkalinity when compared to other corals. However, they have a hard time dealing with swings in PH, Temp, or salinity fluctuations which is no different than any other coral or fish.
The Leather Corals are among the easier corals to harvest they are the easiest coral to kill and one of the hardest corals for someone new to the hobby to identify as a potentially died coral.
