Nerite or Mystery Snails: Snails make wonderful cleanup teams. A single nerite snail will help keep algae under control.

Purification: 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 resist heavy currents.
Heating unit: Most exotic fish require a stable temperature level between 24 ° C and 26 ° C(75 ° F-- 78 ° F ). A little 25-watt submersible heating system is normally adequate for a 19-litre volume.
Lighting: Simple LED lights are ideal. If you wish to grow live plants (like Anubias, Java Fern, or Bucephalandra), make sure the light has actually a spectrum fit for plant development.
