tank paint

i have a 40 breeder and i have 2 bearded dragons the same age but one is abnormaly larg so i have the small one in side a 10g tanks inside to 40 breeder i was going to paint to 10g but i did not know if i should use paint or what kind of paint i should use ir if there is a color that would iritate them so please tell me what i could do to keep them from having eye to eye contact but me still being able to keep the 10g inside to 40g

Tape construction paper on the smaller tank to block the view.

I wouldnt put to much work into it as I started out with a 10g at first too and it isnt big enough for very long. I'm still trying to figure out why you have the 10 g inside the 40. If you only want 1 cage then just put a divider in the middle of the 40. Then you can use the 10 for superworms or roaches or whatever you like to feed them.

If you want it to look more realistic, put on background. They sell them at pet stores usually with the fish section. And once the little guy grows out ofthe 10gal you can attach it to the back of the 40 and it'll look great!

ok thanks
