LPS corals

beginner

Frogspawn coral

Euphyllia divisa

Quick reference

Min tank size

20 US gal

20 gal — most forgiving Euphyllia. Stable nano-reefers run them successfully in 10 gal AIOs.

PAR

50–150 µmol/m²/s

Flow

medium

Placement

Mid-tank or lower rockwork. Tolerates more light than torches but still wants indirect flow.

Temperature

76–80 °F (24–26.5 °C)

Salinity

1.025–1.026 SG

pH

8.1–8.4

Alkalinity

8–10 dKH

Calcium

420–440 ppm

Magnesium

1,300–1,400 ppm

Feeding

Photosynthetic. Optional spot-feeding 1× week with mysis or LPS pellets. Will accept food at night when polyps fully extend.

Compatibility

Same-genus Euphyllia generally OK to touch. 4–6 inch sting range. Don't mix with non-Euphyllia LPS (chalices, hammers from a different parent colony) without buffer space.

What kills it

Alkalinity swings. Brown jelly. Bristleworms in the branching skeleton. Aiptasia outcompeting in the early stages.

Common mistakes

  • Underestimating the colony's full extension when fragging — leave 6+ inches of space.
  • High flow placement causing tentacles to retract permanently.

Equipment & food for this species

LPS appreciate weekly target-feeding. CoralRx dip on new frags catches brown jelly and bristleworm hitchhikers.
