pacman frog?

I know you say some people do it, but I would keep the frog away from gravel because he will likely swallow some of it, which could lead to a gut blockage. I used to keep Pacman frogs in shallow water but not with gravel. A good substrate is coconut fiber. The diet you describe is fine but make sure to gutload the crickets. This will mean that the frog gets a lot more nutrients than a standard cricket provides. I'm not talking about vitamin/mineral supplements, but protein, etc.

It's not the best idea and I'd stay away from it. Those guys eat everything that can fit in their mouths and the rocks or gravel won't digest.
