Himantura granulata
Family: Dasyatidae ยท Rays & Stingrays
Also known as: Mangrove Whipray, Granulated Stingray
The Bluntnose Stingray is a distinctive Indo-Pacific ray characterized by its heavily granulated skin texture, which gives it a rough, almost sandpaper-like appearance. Its disc is relatively small with a blunt, rounded snout, and its dorsal coloration ranges from grayish-brown to dark brown. The long, whip-like tail bears a venomous barb.
In the aquarium, this species requires a spacious tank with a deep sand substrate and open swimming areas. Like all rays, it is sensitive to water quality and demands excellent filtration. The granulated skin texture makes this ray particularly susceptible to bacterial infections if water conditions deteriorate, so maintaining pristine water quality is essential.
This is strictly an expert-only species. It requires prior experience with elasmobranch husbandry, including knowledge of proper feeding techniques, water chemistry management, and safe handling practices around the venomous tail barb.
Feed a varied diet of fresh and frozen seafood including shrimp, squid, clam meat, and small fish. Place food directly on the sand bed near the ray. Feed 2-3 times daily and supplement with vitamins.
Peaceful with fish too large to consume. Avoid aggressive species and small bottom-dwelling invertebrates that may be eaten.
