Care

Size: It reaches about 89 cm and needs a very large, long system: it is for public-aquarium-sized systems, not home aquaria. Like other guitarfish, it needs a sand bed, lots of open swimming room and little rockwork. 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. CITES: the Wikipedia article does not mention CITES, but the family Rhinobatidae (guitarfishes) was added to CITES Appendix II in 2022 (in force 2023); confirm the current listing before selling. In Great Britain, CITES Appendix II species are Annex B under the wildlife trade regulations, so sellers must be able to show the fish was legally imported or captive-bred and keep the paperwork. 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

Like other guitarfish it eats bottom-living crustaceans, molluscs and small fish. Offer chopped shrimp, clam, squid and fish.

Compatibility and tank mates

Not reef safe: will eat crustaceans and small bottom fish.
