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

Dolphinfish 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 1.00 m (length). It shares a biome and an enclosure type with 10 other species, so it can be mixed into a shared enclosure — 4 of those pairings are confirmed by Frontier's own text.

Enclosure and barrier requirements

Dolphinfish needs a Aquarium enclosure and accepts the Open Sea biome. The barrier requirement is Grade 2 · 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 Dolphinfish?

6 launch species share both a biome and an enclosure type with the Dolphinfish, so they are the only candidates for a mixed habitat. Of those, 4 are confirmed group-living by Frontier's own text and 2 are unverified — both are listed rather than presented as equally safe.

Species	Biome	Enclosure	Verdict	Evidence
Humphead Wrasse	Open SeaReef	Aquarium	Likely OK	Humphead Wrasse “Humphead wrasse are generally solitary, although may live in pairs or small groups temporarily for the purpose of breeding.”
Ocellated Eagle Ray	EstuarineOpen SeaReef	Aquarium	Likely OK	Ocellated Eagle Ray “Ocellated eagle rays may be solitary or loosely social. They are often seen in groups for the purposes of feeding, breeding and travelling.”
Pacific Sardine	Open Sea	Aquarium	Likely OK	Pacific Sardine “Pacific sardines live in shoals which may be made up of thousands if not millions of individuals.”
West Indian Manatee	EstuarineLakes & RiversMangroveOpen SeaWetlands	Aquarium	Likely OK	West Indian Manatee “Manatees are semi-social. They are likely to gather in groups for feeding and mating, and will interact with others when they meet…”
Indo-Pacific Sergeant	Open SeaReef	AquariumExhibit	Unverified	Frontier has not stated a social structure for this species.
Pacific Bluefin Tuna	Open Sea	Aquarium	Unverified	Frontier has not stated a social structure for this species.

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

4 of the species that accept the Open Sea biome cannot share an enclosure with the Dolphinfish, 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
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.”
Ocean Sunfish	Open Sea	Aquarium	Ocean Sunfish is solitary “Ocean sunfish are solitary animals.”

Close, but ruled out by enclosure type

2 species share at least one biome with the Dolphinfish 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

Dolphinfish is classed as Social in Frontier's Social & Reproduction notes: “Dolphinfish are generally social and schooling fish, especially when they are young or of similar size. Juveniles and smaller adults often travel in large, fast-moving schools, which helps t…” On size the game lists 1.00 m (length) for the male and 1.00 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.
