Moon Jelly is one of the 130 Planet Zoo 2 launch species. It is housed in a Exhibit habitat, accepts the Estuarine / Open Sea biome, carries a no barrier requirement and is listed at no published size. It shares a biome and an enclosure type with 2 other species, so it can be mixed into a shared enclosure — 1 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.

Moon Jelly needs a Exhibit enclosure and accepts the Estuarine / Open Sea 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.
2 launch species share both a biome and an enclosure type with the Moon Jelly, so they are the only candidates for a mixed habitat. Of those, 1 are confirmed group-living by Frontier's own text and 1 are unverified — both are listed rather than presented as equally safe.
| Species | Biome | Enclosure | Verdict | Evidence |

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.
No other launch species shares a biome with the Moon Jelly.
Nothing to exclude: no other launch species shares a biome with it.
18 species share at least one biome with the Moon Jelly 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.
African Penguin, Blacktip Reef Shark, Dolphinfish, Giant Grouper, Golden Trevally, Great Hammerhead, Greater Flamingo, Hawksbill Turtle, Humphead Wrasse, Indian Ocean Oriental Sweetlips, Indo-Pacific Leopard Shark, Ocean Sunfish, Ocellated Eagle Ray, Pacific Bluefin Tuna, Pacific Sardine, Red Lionfish, Saltwater Crocodile, West Indian Manatee
Moon Jelly is classed as Social in Frontier's Social & Reproduction notes: “Although moon jellies may be found in large aggregates, they are not social and are usually found together because of ocean currents and shared food sources.” 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.
Can Moon Jelly live with other animals in Planet Zoo 2?
Yes. 2 launch species share both a biome and an enclosure type with Moon Jelly, and 1 of those are confirmed as group-living by Frontier's own text. Keep the Estuarine / Open Sea biome and the Exhibit habitat constant and mixing them is a data question, not a guess.
What biome does Moon Jelly need in Planet Zoo 2?
Moon Jelly accepts 2 biomes: Estuarine / Open Sea. Biome is not cosmetic — a species placed outside its listed biomes will not thrive, however good the enclosure looks.
What barrier grade does Moon Jelly need?
Moon Jelly needs no barrier grade. With no barrier grade in the data, this species is shown behind glass in an aquarium or exhibit rather than behind a paddock fence.
Is Moon Jelly in the base game or Deluxe?

How big is Moon Jelly in Planet Zoo 2?
Moon Jelly is listed at no published size, with an adult male weight of not published. The game does not publish a body length for this species.
Is Moon Jelly social or solitary?
Frontier's own Social & Reproduction text classes Moon Jelly as social. “Although moon jellies may be found in large aggregates, they are not social and are usually found together because of ocean currents and shared food sources.” That classification is what decides most of the compatibility verdicts on this page.
