Good luck on the pieds!

May I add another related question to this thread?
For two hatchling KIngs, I chose two "Hefty" brand 15qt tubs with latch locks on the ends mainly because these seemed to have the stiffest construction.
The Sterilite tubs seemed very flimsy, and were mostly cracked already anyway.

The Heftys, however were only avail with a solid black cover, and a smokey tinted tub base. I can see the animals through the plastic, and the tubs are getting light from all sides for now. Is enough light getting through to them?

Thanks.
