Notes: Triggers have earned a reputation as aggressive fish in the aquarium trade. This is sometimes well earned and other times not quite fair. They will usually pick on smaller fish that are introduced after they have become established in an aquarium. If adding more triggers, smaller additions should be more aggressive species and larger trigger additions should be an equal or less aggressive species.
