Phailozoo 120 Gallon Reptile Enclosure (48"×24"×24") — the 4x2x2 Forever Home for Adult Boas

The whole hobby standardized on one footprint for adult boas and ball pythons: 4x2x2. This is Phailozoo's 120-gallon version — the enclosure class our Reptile Lab was missing at the top end. 48"×24"×24" (120 gal): the forever-home size for adult Colombian red-tails, ball pythons, and rainbow boas Stackable: build a wall of enclosures as the collection grows, one footprint at a time 4.6-star rated: and ranked a category winner in 120-gallon roundups — the qualifying pick in its class (the 3.9-star alternatives didn't make our cut) The step up: our REPTI ZOO enclosures cover smaller animals; this is where they graduate to Good to know: plan the heat at the same time — a 100W ceramic emitter on a thermostat (both in our Reptile Lab) is the standard pairing for a 4x2x2. Buy the last enclosure first. That's the ShopperBear way.
