Beautiful! I love brb's. Mine was just born this season and it's hard to imagine her getting that big!! She's such a small little noodle.
My Willow loves to grab stuff in her tail. You can kind of see the cypress bedding on my hand there. Whenever I pull her out, she wraps a bunch of it up in her tail and it's near impossible to pull it free.
As far as tub setup... Willow has a large water bowl, a humid hide and one of those black box hides. She spends 95% of her time on the cool side in her black hide. She very rarely goes into her warm hide. I don't know if that's normal at all.
Yours is beautiful, though! Congrats! I can't wait until my girl gets that big.
