Shovelnose Sturgeon

The Shovelnose Sturgeon, scientifically known as Scaphirhynchus platorynchus, belongs to the Oddballs family group. Adults reach a maximum size of approximately 85 cm and have a depressed body shape with a slow growth rate. Classified as mostly peaceful, this species primarily occupies the bottom zone of the aquarium and produces a extreme level of biological waste.

To thrive, the Shovelnose Sturgeon requires a freshwater only aquarium with a minimum volume of 3000 litres and a tank length of at least 300 cm. Water temperature should be maintained between 10°C and 22°C, with a pH range of 6.8–8 and a general hardness of 8–20 dGH. A high water flow is preferred.

The Shovelnose Sturgeon is a rewarding species to keep, provided its core environmental needs are met. This species is available in 2 varieties: Adult (Standard) and Juvenile (Grow-out). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.

When setting up an aquarium for the Shovelnose Sturgeon, a high water flow best suits their natural preferences. Because this species occupies the bottom zone, the aquarium layout should prioritise sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour and smooth gravel or rounded substrate to protect their sensitive barbels. Keepers should note that a tight-fitting lid is essential, as this species is a known jumper and expect substrate disturbance, so lightweight décor should be secured.

Classified as mostly peaceful, the Shovelnose Sturgeon is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, any fish small enough to fit in its mouth will likely be eaten, ornamental shrimp are not safe companions, and their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the bottom zone can help reduce competition and territorial overlap.

Shovelnose Sturgeon is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide someone who understands its individual space requirements. It makes the most sense for a hobbyist who will actually build around its needs, especially sand.

The most common mistake is treating Shovelnose Sturgeon like any other community fish and skipping the soft sand it needs to forage safely. Another frequent problem is forcing it into an over-busy community when it would do better with more room or more deliberate tankmate choices.

The Shovelnose Sturgeon is a predatory species that will readily consume small fish, so nano or bite-sized tankmates should be avoided and will hunt and eat ornamental shrimp, making it unsuitable for shrimp-focused setups.
