What we are sure of it is habitat. Flows like river rapids, with clear waters and lush vegetation.

Aquarium conditions

The size of the aquarium depends on some of the copies that we will introduce, but we can establish that an aquarium from eighty liters would be nice, and should ideally have a 150 liters, especially if we want to have more than one male.

planted aquarium

The aquarium should be well planted, enough places where you can hide, as it tends to hide during the day. They appreciate, let's pretend that in aquarium water streams whence.

To encourage spawning, Aquarium parameters should be adjusted a pH between 6,5 Y 7, with a temperature of 27 ° C and a hardness of the water between four and 10 ° dGH.
