Cant be exactly sure but this is whatit looks like cant see the colorsof the coral to be close enough
Euphyllia divisa
This species, known to hobbyists as the frogspawn coral, is found In the waters of the central Indo-Pacific, Australia, Southeast Asia, southern Japan islands and East China Sea, the Solomon Islands, Fiji, and Palau (Turak
et. al. 2008c, Randall 1995). It also has very long tentacles when fully extended, but rather than end with little hammers, they're covered with short branches that are tipped with small rounded knobs. The tentacles are sometimes almost clear, but are typically various shades of fluorescent green and brown like those of
E. ancora, with the knobs on the tentacles being lighter/different colored too, often being cream colored. It also has a flabello-meandroid skeleton.\
