Does my tub look ok?

[shelliebear]

I hope my mom doesn't see this post...I feel bad, but I couldn't take it anymore.
The photos I have seen of snake cannibalism were too much. They were stuck in my head. These snakes are my babies, not just a pet.
I was freaking out about still having Cleo and Madison housed together.
My mom didn't want me to put them in tubs, so I have Nergal and Cleo in separate tanks, and I took my clothes out of one of my sterilite carts and put Madison in the top drawer.
I put Aspen shaving down to cover it, slid a heat mat underneath with a piece of construction paper over the top of the heat mat (so it isn't directly touching the tub). I put a metal container in and filled it with water, and put a Zilla hide log on the hot spot. I'm going to try to make her another hide for the cool spot.
I don't have a thermostat yet to control the temperature. My mom said at one point she would buy another tank for Madison since she didn't want her in a tub, but never did, and now I can't find anymore good Craigslist deals on them.
I couldn't stand it anymore. I had to do something. I don't want any of my babies to die, be stressed, or eat each other.
So, does this tub look ok? Money permitting I will buy a thermometer and thermostat, and make her another hide.
I think it looks ok though. She has lots of room.
Here are photos:



Can take more photos if needed.
