Care

Size: It reaches about 100 cm and needs a very large, long system: it is for public-aquarium-sized systems, not home aquaria. Needs thick sand and sparse decor. Water: 16–22 °C, pH 8.1–8.4, salinity SG 1.023–1.026. These are general marine aquarium figures for a temperate 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. Identification: a different species from Torpedo sinuspersici, which the list also calls "marbled electric ray". This entry was written from the list only; check details before relying on it. Selling: our policies require the adult size and long-term tank needs to be stated clearly in the listing. Large fish must travel by a specialist live-animal courier (see the Livestock shipping guide). Sources: Wikipedia, List of marine aquarium fish species (en.wikipedia.org/wiki/Listofmarineaquariumfishspecies). Checked October 2026.

Diet

An ambush predator of fish that usually takes only moving food. Offer live or moving foods, or whole fish moved on a feeding stick.

Compatibility and tank mates

Not reef safe: eats fish and can shock tankmates. Best kept alone.
