You can comfortably keep a colony of 10 to 15 shrimp in 19 litres, as their bioload (waste production) is extremely low.Nerite or Mystery Snails: Snails make fantastic cleanup teams. A single nerite snail will help keep algae under control.Nano Fish Species: Very few fish types appropriate for a tank this size. Endler's livebearers (males only, to avoid overbreeding) or Microdevario kubotai (emerald dwarf rasbora) can work, but only if the aquarist is skilled and keeps strenuous water quality.What NOT to Put in a 19-Litre TankTo make sure animal welfare, prevent keeping the following types in a 5-gallon aquarium:Goldfish: Goldfish produce enormous amounts of waste and grow far too big.
