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

Clown Loach is one of the 130 Planet Zoo 2 launch species. It is housed in a Aquarium / Exhibit habitat, accepts the Lakes & Rivers biome, carries a no barrier requirement and is listed at no published size. It shares a biome and an enclosure type with 11 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

Clown Loach needs a Aquarium / Exhibit enclosure and accepts the Lakes & Rivers biome. 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 Clown Loach?

8 launch species share both a biome and an enclosure type with the Clown Loach, 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

3 of the species that accept the Lakes & Rivers biome cannot share an enclosure with the Clown Loach, 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
African Tigerfish	Lakes & Rivers	AquariumExhibit	African Tigerfish is solitary “African tigerfish are best described as asocial to loosely aggregative predators: juveniles show schooling behaviour, while adults are large…”
Axolotl Deluxe	Lakes & Rivers	Exhibit	Axolotl is solitary “Axolotls are solitary in the wild and are happy living alone in captivity. However, unless different in size, they are content with other ax…”
Giant Slippery Frog	Lakes & Rivers	Exhibit	Giant Slippery Frog is solitary “Giant slippery frogs are solitary and do not interact except to mate or compete over mates.”

Close, but ruled out by enclosure type

3 species share at least one biome with the Clown Loach 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

Clown Loach is classed as Not stated in Frontier's Social & Reproduction notes: “In the wild, clown loaches school in groups of 5-20 individuals.” 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.
