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 the Thick Branched Frogspawn Coral is moderately difficult to maintain, with proper water conditions in the aquarium, it will thrive. The Thick Branched Frogspawn Coral requires moderate lighting combined with moderate water movement within the aquarium. At night, its sweeper tentacles can extend up to six inches beyond its base into the reef aquarium surroundings, stinging other species of corals and animals. Therefore, be sure to provide plenty of room between it and other neighboring corals.
The symbiotic algae zooxanthellae hosted within its body supplies the Thick Branched Frogspawn Coral a majority of its nutrition. However, it will benefit from additional food fed weekly in the form of chopped meaty items, micro-plankton or baby brine or mysis shrimp. For continued good health, the Thick Branched Frogspawn Coral will also require the addition of calcium, strontium, iodine, magnesium and trace elements.
