It offers them sufficient space to check out, especially if planted densely. Freshwater Shrimp: Cherry shrimp, Amano shrimp, and crystal shrimp thrive in nano tanks. You can conveniently keep a colony of 10 to 15 shrimp in 19 litres, as their bioload (waste production) is exceptionally low. Nerite or Mystery Snails: Snails make wonderful clean-up teams. A single nerite snail will assist keep algae under control. Nano Fish Species: Very few fish types are appropriate for a tank this size. Endler's livebearers (males just, to avoid overbreeding) or Microdevario kubotai (emerald dwarf rasbora) can work, but only if the aquarist is knowledgeable and preserves rigorous water quality.

Filtering: You will need a little, adjustable hang-on-back (HOB) filter or a sponge filter rated for up to 20 or 30 litres. Ensure the circulation rate isn't too strong, as fish like Bettas battle against heavy currents. Heating system: Most tropical fish need a steady temperature level in between 24 ° C and 26 ° C(75 ° F-- 78 ° F ). A small 25-watt submersible heater is typically sufficient for a 19-litre volume. Lighting: Simple LED lights are ideal. If you desire to grow live plants (like Anubias, Java Fern, or Bucephalandra), ensure the light has actually a spectrum matched for plant growth.
