Comportamiento:

Es un pez normalmente social, que se puede mantener con peces más grandes que el ancho de su boca, ya que por ser un pez carnívoro se comera todo lo que entre en su boca. Es un pez prácticamente ciego que se guia por su olfato. Le gusta nadar en la zona baja del acuario, por lo que se debe decorar con plantas y troncos que le brinden protección pero que no le obstruyan el paso. Si no tiene suficiente espacio y escondites, se mostrara agresivo con los demas compañeros. Es un experto escapista, asi que el acuario debera estar siempre bien tapado. Si se escapa puede vivir varias horas fuera del agua hasta que se seca y se muere.

Reproducción:

El macho puede perseguir por horas a la hembra hasta que logre fertilizar los huevos que después va a depositar uno por uno en alguna planta frondosa. Los alevines deben ser colocados en una pecera aparte después de nacidos, a medida que crecen se recomienda tenerlos c/u de los alevines aparte, para evitar el canivalismo entre ellos.
