Is a 20L tank OK for two adult ADFs?

I have five ADF's in 25-liter aquarium. They are very healthy and reproduce often. I am sure that three or four African Dwarf Frogs can live in a 20 liter tank (of course, without fish and with good filtration).

I think the comments/guidelines are more for those that will only do the bare minimum. Those of us that truly like our charges go way above and beyond those minimums. I look at the housing and wonder if I would want to live there... so with plants, planted and floating, hiding places, basically something to do, those guidelines can be stretched just a bit. You are obvisiouly doing everything right.
