WOW that cream female is gorgeous!! Very very nice pickups!!
My crestie is still in a large critter keeper, but she's growing fast so I'll have to move her to a tub soon. I'm also interested in any pointers from others who have actually made crestie tubs, since I was planning on following the sticky here too. I would think that whatever you use to cut the hole would work as long as it's sharp enough and you score the line enough times. Although I have read other reviews of certain brands of plastic scorers that said they just weren't sharp enough.
