Thick Branched Frogspawn Coral
The Thick Branched Frogspawn Coral is a species of Euphyllia coral rarely seen in the aquarium hobby. Its fleshy round-tipped polyps instantly identify Euphyllia yaeyamaensis as a “Frogspawn” coral but upon careful observation, the unique features of this species become evident. Even when fully expanded, the tentacles of the Thick Branched Frogspawn Coral are notably short and thick, giving it a squat, compact appearance.
Though moderately difficult to maintain, this coral thrives under proper water conditions. It requires moderate lighting and moderate water movement within the aquarium. At night, its sweeper tentacles can extend up to six inches beyond its base into the reef aquarium.

I’ve had this coral for three months now and it’s doing well in my reef tank. The compact shape and unique polyps stand out among other corals. I keep moderate lighting and water flow as recommended. It’s not easy to grow, but once established, it’s a beautiful addition.

The coral looks different from other Frogspawn types. Tentacles are short and thick, which is unusual. I adjusted my lighting to moderate and added some gentle water flow. It’s still developing, but I’m happy with how it’s growing.
