Will this terrarium work?

[Zak]

Ok, so I have been thinking of methods to separate land and water for the red eyed tree frogs I hope to get in a month, and I came up with this "blueprint"...

I would like to highlight that i purposely want to water level to be a tiny bit below the peek of the gravel, hopefully to stop the substrate from becoming soaked, would this work?

Also, the water will be about 2.5 inches deep with stones and plants to stop the frogs from drowning, but I was wondering if I could put any fish/shrimps in here?


Heres my pic btw, forgive the bad attempt at drawing it but macs don't have paint lol...
