Juveniles and subadults should be provided with a well-decorated, planted aquarium with driftwood roots and branches. Larger individuals are relatively unfussy, although some surface cover in the form of floating or overhanging vegetation or branches is appreciated. The addition of marine salt is not required at any life stage.
Datnioides spp. typically produce a lot of waste so the use of large external filters is essential. If possible buy units with built in heaters or at least fit a sturdy heater-guard since adults have been known to damage submerged equipment. Sump systems also work well, and the heater can be housed within.
They do not travel well and can be tricky to stabilise post-import, often refusing to feed and continuously exhibiting a colour pattern indicative of stress but also displayed at night. In D. undecimradiatus the dark body bars fade, leaving only the margins or a series of spots distinctly visible, with the majority of the body greyish, brownish, or blackish.
