limentación:
Omnívoro, es un pez muy voraz. Acepta perfectamente comida en escamas, aunque se debe alternar con alimento fresco y/ o vivo, como gambas, trozos de pescado y crustáceos, o peces que le quepan por la boca (cuando es más grande).

Comportamiento:
Los juveniles pueden vivir en un acuario comunitario, pero no debe estar con peces que le quepan por la boca, ya que podría engullirlos.

Pez activo, requiere de espacio para nadar. Muy nervioso, con algún acercamiento al acuario o golpe al vidrio del mismo, se estresa muchísimo y nunca se acostumbra a reconocer a su propietario. Si se estresa y asusta nada rápidamente y se estrella contra las paredes del acuario, provocándose en ocasiones lesiones, que van desde un simple aturdimiento por algunos minutos, hasta lesiones serias.

Hay que tener cuidado su manejo, ya que los aletazos que este pez puede llegar a dar cuando alcanza un tamaño considerable pueden causar heridas. De igual forma se debe tener precaución con las espinas de las aletas.

Reproducción:

No se ha conseguido de forma natural en acuarios, solo se ha conseguido inyectando hormonas.
