A 24×18×18" is about 60×45×45 cm, a floor-space enclosure, so it suits ground-dwelling species that need room to roam. Here is what suits it as a permanent adult home, from most to least common.
27 species can suit a 24×18×18" as an adult, based on conservative minimum footprints. Bigger is always better.
Cool, humid, low-light terrestrial gecko needing plenty of hides and no bright basking zone.
Tiny arboreal, all-female colony gecko needing a planted vertical vivarium with plenty of cover.
A tiny arboreal bamboo-dweller; a planted, vertical 30x30x45 cm (12x12x18 in) bioactive viv suits a pair, with bamboo and cork to climb.
Cool, humid woodland amphibian needing a low, planted, heavily-hidden floor with deep damp substrate; keep it cool, never heated.
Small, shy terrestrial species needing a humid, heavily planted setup with a water area and hides.
Terrestrial burrowing amphibian needing a low, cool floor with deep, damp substrate; floor space over height, and no heat lamp.
Small, cool-and-humid, delicate; a densely planted viv suits a pair, keep them low-stress.
A 2×1.5 ft footprint with deep substrate, depth matters for a burrower.
A small, low 2x1.5ft floor with deep substrate for this cool-loving burrower.
A large arboreal treefrog needing height and sturdy broad-leaf plants.
A small, active arboreal frog; a couple suit a planted vertical terrarium.
A planted bioactive viv; a small group fits an 18x18x18 in, species and numbers vary.
Semi-aquatic and social; a small group needs a land area plus a clean water section.
Hardy small arboreal frog needing height, cover and a seasonal cool period.
Tiny, diurnal, toxic-in-the-wild frog; a bioactive floor-focused viv suits a small group.
A sit-and-wait ground frog: floor space and burrowing depth matter, height does not.
Arboreal and delicate; a planted, humid vertical viv suits a small group.
Terrestrial and stocky; prioritise floor space and a moisture-holding substrate.
A chunky arboreal frog; one adult suits a 45x45x45 cm setup, more height is welcome for climbing.
Arboreal: needs vertical height, anchor points and good airflow.
A gentle detritivore needing deep, moist substrate to burrow, floor space over height.
Social; needs a long tank with very deep substrate for moulting, plus fresh and salt water.
Large, very fast arboreal tarantula for experienced keepers; prioritise vertical space.
Arboreal and docile; give height with cork bark and a tall water-tight burrow.
Needs height at least 3x its body length to moult safely; one per enclosure.
Fast arboreal genus; height and cover over floor space, keeper experience recommended.
Harmless arboreal arachnid that presses flat against vertical cork bark; needs height.

Group sizes, sex ratios and exact needs vary by species, always confirm with an up-to-date care sheet, an experienced keeper or an exotics vet before you buy an animal or an enclosure. baskr provides husbandry guidance, not veterinary advice.
