Yaeyama Euphyllia

Yaeyama Euphyllia was first described in 1980 by Shohei Shirai, a stony coral in the Euphylliidae family whose species name honors Japan's Yaeyama Islands. It belongs to the same group as Hammer and Frogspawn corals, but stands apart with short, densely packed tentacles that give it a distinctive, textured look as the polyps sway in the flow. It's seen less often in the trade than other Euphyllia species, making it something of a collector's favorite. Rated as suitable for intermediate keepers, it generally follows the same care approach used for Hammer and Frogspawn corals, so aquarists with experience keeping those should find it approachable.

About Yaeyama Euphyllia

Yaeyama Euphyllia is a Euphylliidae stony coral described in 1980, known for its short, densely packed tentacles and limited trade availability. Suited to intermediate keepers using Hammer/Frogspawn-style care.

7 things to know before welcoming a Yaeyama Euphyllia

1Short, Densely Packed Tentacles
Yaeyama Euphyllia is known for its short tentacles that sit closely packed together, giving it a texture unlike other Euphyllia species. Watching the tentacles sway gently in the flow is one of the pleasures of keeping this coral.
2Care Follows Hammer/Frogspawn
General husbandry is said to follow the same approach used for Hammer and Frogspawn corals. If you've already kept those species, you'll likely find this one approachable using similar routines.
3Rated for Intermediate Keepers
This species is rated as suitable for intermediate keepers. Some background in basic coral husbandry and water quality management helps keep it stable long-term.
4Less Common in the Trade
Within the Euphyllia family, this species is said to appear less often than other members. Since availability can be limited, it helps to have your setup and care plan ready before you find one.
5Give Tentacles Room to Extend
Like other Euphyllia corals, extended tentacles can irritate neighboring corals they come into contact with. Leave enough space between this coral and its neighbors when choosing a placement.
6Adjust Flow and Lighting
Because the tentacles sit close together, flow that's too strong can keep them closed, while flow that's too weak can let debris accumulate. Watch how the polyps open after placement and fine-tune flow and lighting accordingly.
7Acclimate Carefully After Arrival
Newly arrived specimens are stressed from transport, so a slow, careful acclimation and a calm environment afterward are important. Keep an eye on its condition for the first few days before settling into a feeding routine.
