In my zero-maintenance tanks, I rely on a nearly sealed environment and
plants for the stability. They have very few fish in them.
I'm able to run them at ultra-low maintenence levels for years by letting
the plants grow emersed, providing them with direct access to CO2 and
allowing lower light levels because I don't have do deal with reflective
losses at the surface of the water (I get reflective gains instead between
the surface and the light).
I'd recommend letting your plants determine which does best in the tank
(actually, if you lower your maintenence, this will happen naturally).
Also, don't go adding too many fish. A zero maintenance tank should be
able to maintain its fish almost wholly on the recycled nutrients in the
tank. I only feed a tiny amount twice a week to mine to keep the mineral
Duckweed is a good indicator plant for a zero maintenance tank.
Although I've had a lone cardinal tetra survive on what it could find in a
20g zero maintenance tank, I don't recommend it. This fish probably
survived mainly by grazing on tiny crustacea in the tank while they lasted.
It died after about 6 months because of a nasty micobacterium infection
that it came from the aquarium store with 2 years earlier.
