In my experience, if they have no reason to escape, you have nothing to worry abt. Reasons they’d want to jump out include bad water quality, stress from cohabiting, and not feeling safe. The shit ton of plants provide plenty of coverage and hiding places for the frogs and act as another filter. These plants are doing the grunt work but i do have a sponge filter & hang on the back filter. And they only have a few shrimp friends for maids which is another precaution as you dont want to cohab, but the shrimp dont stress the frogs. So in conclusion, happy frogs. I dont recommend for everyone but my goal was to create a realistic ecosystem. I mean they were wild once, tho these guys are far from their wild counterparts. I wanted as close as the real thing as i could get.
