The Spoonbill fish or American paddlefish (Polyodon spathula) is a species of basal ray-finned fish closely related to sturgeons in the order Acipenseriformes. Fossil records of paddlefish date back over 300 million years, nearly 50 million years before dinosaurs first appeared. Spoonbill fish are smooth-skinned freshwater fish commonly called paddlefish but are also referred to as Mississippi paddlefish, spoon-billed cats, or spoonbills also known as “spoonbill” because of its duckbill-like snout. They are one of only two extant species in the paddlefish family, Polyodontidae.
There were two species of paddlefish, the American and the Chinese. No Chinese paddlefish (which grew much larger than the American species) have been seen for several years now and the species is sadly almost certainly extinct. The cause of its demise is probably water pollution and the dams on the Yangtze, the only place it lived. Their body size for adults is 1,100-1,600 mm total length and can live in 30 years.
The life of a Spoonbill fish is, unfortunately, not without its threats. The species has been listed as vulnerable by the International Union for Conservation of Nature (IUCN), primarily due to overfishing and habitat loss. The Spoonbill fish, once plentiful, is now reduced to just a fraction of its original population size. The paddlefish’s large size and eggs, which are often harvested for caviar, make them a target for overfishing. Additionally, the construction of dams, levees, and other man-made structures has severely altered their natural habitats.
Spoonbill fish – American paddlefish in aquarium
American paddlefish are rarely seen in aquariums, as they grow very large and require a lot of space. These fish require a significantly large amount of space to move freely and comfortably. Thus, they are typically kept in public aquariums rather than home aquariums., such as the OdySea Aquarium in Scottsdale, Arizona.
Paddlefish are filter feeders, so they need a lot of water to move food particles through their elaborate filtering system. Their long, paddle-shaped snout is covered in electroreceptors that help them to detect the weak electrical fields created by their prey.
American paddlefish can grow up to 6 feet long and weigh over 100 pounds. They are an ancient fish species, with fossils dating back over 300 million years.
Here are some of the reasons why American paddlefish are not commonly kept in aquariums:
- They grow very large, reaching up to 6 feet long and weighing over 100 pounds.
- They require a lot of space, as they need a tank that is at least 100 gallons for each fish.
- They are filter feeders, so they need a lot of water to move food particles through their filtering system.
- They are sensitive to water quality, so they require very clean water.
- They are not very hardy fish, and they can be susceptible to disease.
If you are considering keeping an American paddlefish in an aquarium, it is important to do your research and make sure that you have the proper setup and care requirements. These fish are not for everyone, but they can be a rewarding addition to the right aquarium.
Additionally, these fish are filter feeders, relying on zooplankton as their primary food source. Their gill rakers act like a net, capturing tiny organisms as the fish swim with their mouths open. Replicating this diet in an aquarium setting can be challenging, requiring careful management of the tank’s ecosystem or provision of a specialized commercial diet.
Minimum Tank Size: 300 gallons
Care Level: Difficult
Temperament: Peaceful
Water Conditions: 22-27°C or 72-80° F , pH 6.0-7.5
Diet :
• Swim with their mouths open to strain water through their gill rakers to feed on plankton
• Insects, plankton, bryozoans, sand, and detritus have been found in their stomachs
• Juveniles have large teeth and eat microcrustaceans, insect larvae, and small fish

Water should be used to raise water without chlorine it and overseeing the PH so. In your Tank should organize clearly, because many times the fish swim to track the timber and then leave not a normal, if fish stop swimming, they will die.
Paddlefish eggs are commercially available for at least a century, even though traditionally they have been shunned by connoisseurs. Favor moved to beluga sturgeon in the Caspian Sea. Their glistening eggs, known as pearls, are bigger and firmer, with a sumptuous”soda” of taste when pressed between the tongue and roof of their mouth. The Spoonbill fish A fine yet less expensive alternative to sturgeon caviar.
