Black Devil Stingray Tank Setup
A tank of at least 1650 litres (436 US gallons) works well. Keep the water at 68-84°F with a pH around 6.5-7.5, and set up both cover and open swimming space where they spend most of their time (Mid). They grow to around 60 cm, so plan the tank size and filtration for a full-grown adult rather than the small juvenile you see in the shop.
What Do Black Devil Stingrays Eat?
They're not fussy eaters - feed a varied diet, rotating good-quality dry, frozen, and gel foods rather than the same thing every day, and match the food size to their mouths.
Black Devil Stingray Tank Mates
Requires a large tank and good filtration. The Black Devil Stingray is peaceful, which is the first thing to weigh up when you choose tank mates. At around 60 cm fully grown, it needs tank mates that can hold their own against its size and appetite. Before you buy, run your full stocking list through our stocking calculator. It weighs temperament, adult size, and water needs together, which a single species page can't do on its own.
