Freshwater Shrimp: Cherry shrimp, Amano shrimp, and crystal shrimp thrive in nano tanks. You can conveniently keep a nest of 10 to 15 shrimp in 19 litres, as their bioload (waste production) is incredibly low.
Nerite or Mystery Snails: Snails make fantastic cleanup crews. A single nerite snail will help keep algae under control.
Nano Fish Species: Very couple of fish types appropriate for a tank this size. Endler's livebearers (males only, to prevent overbreeding) or Microdevario kubotai (emerald dwarf rasbora) can work, but only if the aquarist is skilled and maintains rigorous water quality.

What NOT to Put in a 19-Litre Tank

To ensure animal welfare, prevent keeping the following species in a 5-gallon aquarium:

Purification: You will need a little, adjustable hang-on-back (HOB) filter or a sponge filter ranked for up to 20 or 30 litres. Make sure the circulation rate isn't too strong, as fish like Bettas resist heavy currents.
Heating unit: Most tropical fish need a stable temperature between 24 ° C and 26 ° C(75 ° F-- 78 ° F ). A small 25-watt submersible heater is normally enough for a 19-litre volume.
Lighting: Simple LED lights are perfect. If you wish to grow live plants (like Anubias, Java Fern, or Bucephalandra), ensure the light has a spectrum matched for plant development.
