The aquarium must be mature and have a soft sandy substrate in order for this species to burrow. P. doriae should be kept in groups of at least 5 specimens, and with plenty of shady areas and hiding places within the aquarium. It is not unusual to see this species forming a network of burrows beneath rocks, where they will congregate in social groups. They are often observed with just their heads poking out of the substrate. Keep only with other small peaceful fish species.
