You could put a carnivore in there, but there's no guarantee it will catch the gnats. The best way to deal with them is make a gnat trap. Take a small, empty water bottle and cut off the too third. Now, you have 2 options here, either put a little sugar water at the bottom, or a few pieces of fruit. Then place the top into the bottom upside down so the neck is facing down. Place it in the tank for a few days and the gnats should be trapped inside the bottle. I like to use the sugar water method because it sort of simulated a nepenthes pitcher plant
