Will be fine for a hatchling or a juvenile up to about 9 mths old I'd get a 100L to 120L tub , or maybe a 150L tub ( if you can find one ).
They are dead easy to convert to a rearling tub for lizards.
Check it's about 45cm tall , this height works great for mounting a nano hood under the lid for a 26W UVB200 globe with the basking spot top being about 20cm high.
