You can conveniently keep a colony of 10 to 15 shrimp in 19 litres, as their bioload (waste production) is remarkably low. Nerite or Mystery Snails: Snails make fantastic clean-up crews. A single nerite snail will assist keep algae under control. Nano Fish Species: Very couple of fish types appropriate for a tank this size. Endler's livebearers (males just, to avoid overbreeding) or Microdevario kubotai (emerald dwarf rasbora) can work, however only if the aquarist is knowledgeable and keeps extensive water quality.
