I'm interested in getting some Milk Frogs and have heard of people doing very simple setups with just a few inches of water for the substrate. I know this would make it very easy for cleanup as water changes are easier than substrate changes. Does anyone know if this is viable and is there a "best way" of doing it?

I'm also concerned about feeding time. Can I just throw the crickets into the water and will the frogs eat them if they're in the water?

It may ultimately be best to just do a false bottom setup, but I wanted to explore this option first. Thanks!

P.S - I'm doing this in a 20 gallon high aquarium with screen lid.
