Care
Tank and decor: at 200 cm adult length this shark outgrows home aquaria and is for public-aquarium-sized systems. The list quotes a minimum of 5750 US gallons (about 21760 litres), and as an active swimmer it needs a long, round-cornered or oval system with open swimming space. Strong filtration and a secure cover are essential. Water: our sources give no species-specific figures, so the values here are general marine aquarium guidance, not species-specific: 24–27 °C, pH 8.1–8.4 and specific gravity 1.023–1.026. Sharks are sensitive to copper and many other medications. Behaviour and identification: a requiem shark with black-tipped fins. The list says it must keep swimming to breathe, is easily startled and may jump out of open tanks or hit the walls, which can be fatal. At up to 200 cm it is for public-aquarium-sized systems only. 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).

Diet
Carnivorous. Feed a varied diet of meaty marine foods such as squid, prawn, mussels, clams and fish pieces, with a vitamin and iodine supplement to help prevent goitre. Feed two or three times a week to appetite rather than daily; overfeeding causes fast growth and health problems.
Breeding
Our sources for this page give no species-specific breeding details.
Compatibility and tank mates
Not reef safe: a fish-eating predator. Only for public aquaria with large tankmates.
