Thick Finger Leather Coral
The Thick Finger Leather Coral, also known as Sinularia Coral, Finger Leather, or Trough Corals, is a popular choice for reef aquariums. It features various shades of brown or green with white or gold polyps. Due to their similar appearance, many species are difficult to distinguish — all resemble a mushroom or toadstool shape with a distinct stalk and capitulum (cap).
As the coral matures, it develops a folded or layered appearance. These corals are generally peaceful but require adequate spacing from other corals to prevent competition or potential toxin release. Some species may produce toxins harmful to other reef inhabitants.
Thin specimens from Indonesia are considered easy to maintain and are suitable for both beginner and experienced reef aquarists.

I bought this coral for my first reef tank and it has been thriving after a few weeks. The color is natural and it looks great against the background. I kept it in a well-lit area and it hasn’t shown any signs of stress. It’s a good starting point for new reef keepers.

The coral arrived healthy and has grown slightly since setup. I noticed it’s a bit more active than other types, so I made sure to keep it away from other sensitive corals. It’s not the most colorful, but it’s stable and looks natural.

I’ve had this coral for over three months now. It’s grown a bit and now has a folded look — exactly as described. It’s peaceful and doesn’t interfere with my other corals, though I keep it well spaced.
