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

American Bullfrog is one of the 130 Planet Zoo 2 launch species. It is housed in a Exhibit habitat, accepts the Lakes & Rivers / Wetlands biome, carries a no barrier requirement and is listed at 0.12 m (length). It shares a biome and an enclosure type with 13 other species, so it can be mixed into a shared enclosure — 0 of those pairings are confirmed by Frontier's own text.

Enclosure and barrier requirements

American Bullfrog needs a Exhibit enclosure and accepts the Lakes & Rivers / Wetlands 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 American Bullfrog?

8 launch species share both a biome and an enclosure type with the American Bullfrog, so they are the only candidates for a mixed habitat. Of those, 0 are confirmed group-living by Frontier's own text and 8 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

5 of the species that accept the Lakes & Rivers / Wetlands biome cannot share an enclosure with the American Bullfrog, 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.

Close, but ruled out by enclosure type

21 species share at least one biome with the American Bullfrog 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

American Bullfrog is classed as Not stated in Frontier's Social & Reproduction notes: “American bullfrogs will tolerate each other if there is enough space. They are known to gather in large groups during the breeding season, but males are often aggressive towards each other.” On size the game lists 0.12 m (length) for the male and 0.12 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.
