So the two fence lizards I caught are doing good...I have been feeding them primarily ants...they are still small but the one is growing. I was curious as to how often I should be cleaning the tank and what the best way to do so is? It's a 20g tall with half rock and half sand, it has some moss and some tree plants. The lizards are about 1 inch each in size. Another thing is what else can I feed them at such a small size?

Thanks in advance!

Tiny just hatched crickets, usually called pinheads could work. Maybe Phoenix worms, but they may be a little too big.

I know with the leopard geckos they can eat anything that's slightly smaller than their head.

I'll try and find some small crickets.
