Therefore, our aquarium must be equipped with a device that keeps the water at a constant temperature. Consequently, cold water fish should not coexist in these warm waters. The simplest tropical fish to keep are:

  • Small tetras, such as Tetra nEon and the Luminous tetra. They are very resistant colorful fish, and although they are moderately aggressive they can coexist with other species of similar size.
  • The Corydoras are essential to clean the bottom of the aquarium.
  • The crystal fish and the fish zebra they are ideal companions of the small Tetra.

They can also live with vegetarian fish type:

  • Banjo catfish
  • Otocinclo
  • Locha Dojo

A rule that should be followed in freshwater aquariums is that no specimen fits in the mouth of another individual, because this is most likely the end of the first. With which it is convenient that the sizes are even, or that the large specimens are herbivorous.
