Planet Zoo 2 Indian Ocean Oriental Sweetlips — habitat, biome, size & which animals it can live with
Indian Ocean Oriental Sweetlips is one of the 130 Planet Zoo 2 launch species. It is housed in a Aquarium habitat, accepts the Estuarine / Reef biome, carries a no barrier requirement and is listed at no published size. It shares a biome and an enclosure type with 22 other species, so it can be mixed into a shared enclosure — 13 of those pairings are confirmed by Frontier's own text.
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.

Enclosure and barrier requirements
Indian Ocean Oriental Sweetlips needs a Aquarium enclosure and accepts the Estuarine / Reef biomes. The barrier requirement is none at all, and that is the number to check before building: a Grade 4 animal behind a Grade 1 wall is the most common way a first zoo stalls.
Which animals can live with the Indian Ocean Oriental Sweetlips?
16 launch species share both a biome and an enclosure type with the Indian Ocean Oriental Sweetlips, so they are the only candidates for a mixed habitat. Of those, 13 are confirmed group-living by Frontier's own text and 3 are unverified — both are listed rather than presented as equally safe.

Rule: two animals can share an enclosure only when they share a biome and an enclosure type. Likely OK means Frontier's own Social & Reproduction text says both species live in groups; Unverified means the data does not say, so we do not guess. Pair-by-pair table: compatibility chart.
Same biome, but not compatible
6 of the species that accept the Estuarine / Reef biome cannot share an enclosure with the Indian Ocean Oriental Sweetlips, because one side of the pair is officially solitary. These are the pairings people ask about most, so they are spelled out rather than left as an unexplained gap.
| Species | Biome | Enclosure | Why not |
|---|
| Reef | Aquarium | Blackspotted Puffer is solitary “Blackspotted puffers are solitary and territorial, only interacting with conspecifics during the breeding season.” |
| EstuarineMangroveReef | Aquarium | Giant Grouper is solitary “Giant groupers are solitary fish, although they may form temporary aggregations during spawning.” |
| Open SeaReef | Aquarium | Great Hammerhead is solitary “As opposed to some other species of hammerhead, the great hammerhead shark is a solitary animal.” |
| EstuarineMangroveOpen SeaReef | Aquarium | Hawksbill Turtle is solitary “Hawksbill Turtles are solitary and only interact with other individuals to mate.” |
| EstuarineMangroveOpen SeaReef | Aquarium | Indo-Pacific Leopard Shark is solitary “Indo-Pacific leopard sharks are usually solitary, but may gather in large groups on occasion for reasons unknown.” |
| EstuarineReef | Aquarium | Red Lionfish is solitary “Red lionfish are solitary but will gather in temporary harems during breeding events.” |
Close, but ruled out by enclosure type
4 species share at least one biome with the Indian Ocean Oriental Sweetlips but use a different enclosure type — a land habitat against an aquarium or a flying aviary — so they cannot be mixed however well the biomes line up.

Behaviour, size and weight
Indian Ocean Oriental Sweetlips is classed as Social in Frontier's Social & Reproduction notes: “The Indian Ocean oriental sweetlips lives solitarily, in pairs or in small groups and is not a particularly social species.” On size the game lists no published size for the male. Size and weight together decide the minimum habitat footprint, so use the female figure when you are sizing a breeding pair rather than a display animal.
