If you have the time and the money to care for a BTS then I'd say it's pretty good choice for a lizard.

I will state that I have never owned one before, but have cared for some at the reptile sanctuary I volunteer at.. I've even broken up a fight between two (which I will say I caught at the very start of it because I was supervising them until the event in case it happened).

They're pretty awesome lizards, and the super calm ones at the reptile shows are so much fun to pet LOL! If you're looking for some, check if there's any reptile shows/expos that are taking place this year. You might find a lot better luck at an expo and a healthier animal from a reputable breeder.

Good luck, keep up the research
