could u post pix of their bellies? the first one could be Enchi, but a very low quality one. it's currently dull (but orange after shed?), has lotsa dots but enough pattern reduction and fade from the belly that makes me think Enchi. also the girl has a light triangle "head stamp" blushing.

u can raise the temps by putting them in a smaller tub. reducing the volume of air might help increase temps.

i don't think the tongue thing is a birth defect. i remember an noob keeper thought that about her snake and the "controversy". see here: https://ball-pythons.net/forums/show...Disabled-Snake and u know what, it turned out fine. full tongue and the snake started eating. i just think she's stressed and needs more time to adjust to her new surroundings and needs to get back to normal - size, shed and feeding - and that tongue will be flicking at full length.

anyways good job on the rescue/rehome and i wish u guys the best!
