I'm doing this now. I'm having better success with "larger" setups,
though, as small ones tend to get stagnant or dry out rather

My 29g bog tank is filled half-full of water, lots of plants growing emersed,
and I've just put in simple 2mm sandblasting gravel.  Since there 
was room, I've put in some killies.  It has two levels (one 8" deep,
the other 2-3" deep).

I have to add water to the smaller bog tanks (5g) every third day
(it's arid here in Colorado), but I can get away with adding water
to the 29g once a week.

The 29g tank has no filtration, water movement, or supplemental lighting
whatsoever.  It simply sits on the window sill.  It never gets scummy,
I only replace evaporated water (haven't done a water change in 
over a year), and the killies are breeding.  Maybe I got lucky?  All 
my bog tanks have open tops.
