Subnautica 2 Halfmoon
Fish · Coral Reef · Subnautica 2 current build
Overview
A shallow reef fish recognisable by its crescent-shaped tail fin. The Halfmoon is a grazer that feeds on coral polyps and soft-bodied organisms, congregating near large coral formations. It is one of the first fauna a Pioneer encounters after landfall, and one of the most reliably available food sources once Digestive Incompatibility is cured.
Subnautica 2 Halfmoon — Behavior
Passive grazer that ignores Pioneers completely. Schools near large coral structures. Does not flee on slow approach.
◉ Subnautica 2 Scan Data
Fish — coral grazing behaviour confirmed. Passive toward Pioneer under all conditions. Post-adaptation: edible; low nutritional value per unit. High spawn density in Coral Reef starter zones makes this the most consistently available early food fallback.
