I'm thinking of building Natural aquarium for a group of lizards/ pets.

This is what I plan to build,

A plywood aquarium. I just need to know what kind of paint I should use?

It's going to be a colony of frogs, and turtles (small ones) and possible with a lizard / snake.
Should I stick with the paint that is recommend in the video? or should i change the paint to something else??
