Care

Tank: the list gives no maximum size, so no tank estimate is given here. Care matches other Narcine rays: deep fine sand and no rough rocks. Water: 24–27 °C, pH 8.1–8.4, salinity SG 1.023–1.026. These are general marine aquarium figures for a tropical species, not species-specific values from the sources. Keep nitrate low and oxygen high. Safety: electric organs in the disc can deliver a painful shock. Do not handle it by hand, use plastic tools and nets, and take extra care with large adults. Name: the list has no proper common name for this species ("unknown electric ray"). This entry was written from the list only; check details before relying on it. Sources: Wikipedia, List of marine aquarium fish species (en.wikipedia.org/wiki/Listofmarineaquariumfishspecies). Checked October 2026.

Diet

Hard to feed; offer annelid worms, as for other Narcine numbfishes.

Compatibility and tank mates

Not reef safe: eats worms and bottom invertebrates. Can share a tank with its own kind.
