Tank compatibility[edit]

Due to this fish's size it is not ideal for a home aquarium at all. It is best left in the wild or to public aquaria to keep this species. Smaller fish may well be eaten and it is a solitary species.


A predator partial to shellfish and crustaceans, it may also take smaller fish.

Environment specifics[edit]

Requires a very large tank in captivity and only really suitable for public aquariums. While it can tolerate freshwater conditions it spends the majority of it's time at sea, only entering freshwater to spawn.


A bottom-dwelling fish that hunts along the substrate for food using its very sensitive snout.


The Atlantic Sturgeon has an olive-black upper body and a creamy white belly with an elongated body which tapers to a narrow pointed tip at the snout, and lacks scales. It can be easily recognised by five rows of light-coloured bony platelets that run the length of the fish. Possessing no teeth, it uses conspicuous sensitive barbels on the lower jaw to locate prey which are sucked into the mouth.
