Frogspawn Coral

Overview

Frogspawn Coral gets its common name from clusters of branched, bubble-like tentacle tips that resemble clumps of frog eggs. It's a classic reef staple, valued for the way its polyps billow and pulse gently with tank flow, adding constant movement to the display.

Colours typically run through green, gold and cream tones, sometimes with pink or purple branch tips, and every piece is a one-of-one specimen. It shares the branching Euphyllia growth pattern, with polyps extending well past the underlying skeleton.

It is one of the most forgiving Euphyllia for new LPS keepers, tolerating a reasonably wide range of stable reef conditions.

Placement & neighbours

Frogspawn has active sweeper tentacles and needs a clearance of at least 15-20 cm from neighbouring corals in every direction, since it can sting less aggressive species if crowded. It is generally considered slightly less aggressive than Torch Coral but should still be given its own space.

Works well on mid-tank rockwork with gentle, indirect flow; avoid placing directly beneath powerheads.

Health & acclimation

Use a slow drip acclimation given known Euphyllia sensitivity to rapid changes in salinity and temperature. A brief coral dip on introduction is good practice to check for and remove flatworms or small nudibranchs, which can specifically target Euphyllia species. Keep an eye on the base and skeleton for signs of brown jelly infection, a fast-moving bacterial condition that can appear after physical damage or stress and needs prompt manual removal of affected tissue.
