ah okay. so they definitely need a uth? lots of people say leopard geckos need a uth but my house is usually really warm, so i have a heat lamp with red bulb for them to sit under if they need a bit more heat and theyre both thriving. would a BP be okay with that or is a uth the only way to go? just asking as i may sell my geckos and switch entirely over to snakes and if i could use some of the things i already have it'd be awesome haha.
also, what about substrate? what do yous suggest to have in the bottom of the tank?
once again thanks for all the help!
