I already responded to your thread about getting a Northern BTS with an injured tail and that you planned to house it in a tub.
I want to reitarate and as mentioned by OP for those new to keeping BTS: do not get one if you can't afford to give it a large enclosure and veterinary care. This is a given for ANY species but too often I see some owners try to cut corners by housing a BTS in tubs because a breeder or someone else did it, so why not. The reason is that they do observe their surroundings and they do use every inch of floor space given. These are active lizards that enjoy basking and watching what is going on around their tanks.
The upfront cost is expensive for a reason. If you had done your research as claimed, almost every BTS owner swear by their curious nature, the need for floor space, humidity requirements (Appliable to Indos) and that BTS of all types like any new reptile has the potential to carry internal parasites.
