Planet Zoo 2 Clown Triggerfish — habitat, biome, size & which animals it can live with

Clown Triggerfish is one of the 130 Planet Zoo 2 launch species. It is housed in a Aquarium habitat, accepts the Reef biome, carries a Grade 1 · 1m barrier requirement and is listed at 0.40 m (length). It shares a biome and an enclosure type with 21 other species, so it can be mixed into a shared enclosure — 12 of those pairings are confirmed by Frontier's own text.

Enclosure and barrier requirements

Clown Triggerfish needs a Aquarium enclosure and accepts the Reef biome. The barrier requirement is Grade 1 · 1m, 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 Clown Triggerfish?

15 launch species share both a biome and an enclosure type with the Clown Triggerfish, so they are the only candidates for a mixed habitat. Of those, 12 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 Reef biome cannot share an enclosure with the Clown Triggerfish, 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
Blackspotted Puffer	Reef	Aquarium	Blackspotted Puffer is solitary “Blackspotted puffers are solitary and territorial, only interacting with conspecifics during the breeding season.”
Giant Grouper	EstuarineMangroveReef	Aquarium	Giant Grouper is solitary “Giant groupers are solitary fish, although they may form temporary aggregations during spawning.”
Great Hammerhead Deluxe	Open SeaReef	Aquarium	Great Hammerhead is solitary “As opposed to some other species of hammerhead, the great hammerhead shark is a solitary animal.”
Hawksbill Turtle	EstuarineMangroveOpen SeaReef	Aquarium	Hawksbill Turtle is solitary “Hawksbill Turtles are solitary and only interact with other individuals to mate.”
Indo-Pacific Leopard Shark	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.”
Red Lionfish	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

Nothing: every species that shares a biome with the Clown Triggerfish also shares its enclosure type.

Behaviour, size and weight

Clown Triggerfish is classed as Mixed group in Frontier's Social & Reproduction notes: “Clown triggerfish are not social fish. They are primarily solitary and territorial, especially as adults. Individuals usually occupy and defend a specific area of reef that contains shelter and feeding grounds.” On size the game lists 0.40 m (length) for the male and 0.40 m for the female. 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.
