Sturgeon are long bony scale-less fish whose evolution can date back to the Triassic period 245 million years ago! They are some of the largest fresh water fish in the world and though they grow a bit less when kept in a pond (around 1.25m) it is still imperative that the size of your ecosystem pond is sufficient to cater for one of these dinosaurs. As a general rule of thumb it is suggested that your pond should hold in excess of 10,000 litres of water before purchasing a sturgeon is made viable. Despite their appearance, sturgeon are peaceful bottom-dwellers that will happily live amongst other fish species. It is worth keeping in mind that they are however carnivorous and so very small fish such as minnows will be eaten whilst larger fish such as orfe and koi will be perfect companions.
