The greys and I have adapted together, I learned to take Paddy out during dinner time, she will eat ALL of the crickets and gets surprisingly protective and aggressive when food is around. She eats in a large critter keeper while the rest eat out of a bowl in the viv.

I was thinking 2 RETF's in a 20h sounded more reasonable, I would think 3 was pushing it, and even more surprised that some of the care sheets are saying 5 gallons for each one. I still have not totally decided on one yet though, the P. terribilis is really appealing because they're diurnal and yet will still eat crickets fully grown. I know they would be more fun for my kids to watch and would be easier to breed as a project for me.
