Euphyllia is one of the most popular LPS (large polyp stony) coral genera in the reef hobby. Common species: Euphyllia ancora (hammer coral), E. paradivisa (frogspawn), E. glabrescens (torch coral), E. paraancora (branching hammer), E. cristata (grape coral). Care difficulty: intermediate. Light: 100-250 PAR (LPS range). Flow: moderate, NOT direct - too much flow tears the fleshy tissue. Placement: 6-12 inches between Euphyllia pieces (sweeper tentacles extend at night and sting nearby coral). Feeding: target-feed Reef Roids, Coral Frenzy, or finely-blended frozen seafood 1-2x weekly. Common issues: brown jelly disease (cut + dip immediately if seen), parameter swings cause polyp retraction, alk swings >0.5 dKH/24h trigger tissue recession.
