Hi again bvmbics
Just another side note. The optimum range for filter output for a lightly planted community tank is 4-6 x the volume of your tank. You should be looking at 480l/h output flow.
There is nothing wrong with over filtering but I have heard that above 4-6 x the output there is no increase in efficiency, also the current produced by the filter may not be suitable or be too strong for other fish. Danios will be ok I would imagine. Basically just keep your eye on how the fish react to the current.
Some people will be along shortly to recommend some good fish for your 20 gallon once the cycle is complete.
