Pygmies should do well in a filterless aquarium. They can't stand current,
I read its hard on their sensory pores ( things like a lateral line, which
pygmies don't have). The thick plants in these set ups do many things that
make the set up great for pygmies. Lots of plants create shade . Lots of
plants harbor small bugs-infusoria- which are great food for the fry up to
the adults. The obvious thing is the large amount of plants absorb
nutrients in the water , keeping it clean, a must for pygmies. Lastly,
pygmies live in thick vegatation, so by replicating their natural home, they
are more likly to be very happy- healthy and reproduce. I have foam filters
running in my pygmy tanks, but usually they are also packed with plants.
there seem to always be enough naturally occuring food in these tanks. I
can leave them go for a week without feeding, and adults are fed, and fry
are still alive and growing. Like someone else says, it takes some time to
get the tank to this point.
