small live bearers!
dare I say it.... guppies! And endler's live bearers. And mosquito fish. I've kept young animals in my frog ponds in the past. They are a great bug clean up crew for what lands in your tank. And they'd reproduce to replace the fish the terribilis might eat....
Small bettas might also do well depending on the species. I'm fond of the wine red bettas. Basically I recomend slow water - still water - back water species that can handle a wide range in water qualities like the fish I talked about above.
My only think against cloud minnows in that situation (and why I wouldn't recomend zebra/leopard danios which are similar in requirements) is that they are schooling fish, and a 1/2 gallon, even with more gallons of water available under the false bottom/gravel bottom (just not for swimming space) is not enough for a good school (5+). They need more swimming space as they are active fish. They'd live there, but just because they can, doesn't mean they should, and that it'd be best for them.
