Subnautica 2 Halfmoon

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.

⚡ Subnautica 2 Halfmoon — Survival Tips

  • Halfmoon is the most reliably available food fish in the starter biome — collect several before long dives once Digestive Incompatibility is resolved.
  • Low nutritional value means you need multiple per meal; target Harvestmoon for better nutrition if available.
