Planet Zoo 2 Ocean Sunfish — habitat, biome, size & which animals it can live with
Ocean Sunfish is one of the 130 Planet Zoo 2 launch species. It is housed in a Aquarium habitat, accepts the Open Sea biome, carries a Grade 2 · 1m barrier requirement and is listed at 2.50 m (height). It shares a biome and an enclosure type with 10 other species, but the official species data rules out every one of those pairings, so it needs a habitat of its own.
Every figure on this page comes from the official Planet Zoo 2 Zoopedia export rather than trailer footage: biome, enclosure type, barrier grade, size and the compatibility verdicts are all taken from the game's own data.
