 Must it eat the same thing?  Because if not then there are some small lizards that may work (like an anole) since I doubt sincerely that they will ever attempt to take a cockroach of that size, and the crickets they eat shouldn't bother the roaches either.  Outside of that, I'm not sure, maybe go semi-aquatic and put a fish or two in there?
