Sterlet (Acipenser ruthenus)

The Sterlet or Acipenser ruthenus is a large prehistoric looking fish. This strange looking fish has rows of heavy plates along its sides and dorsal area. It also has a tale that looks more like a shark! This species of Sturgeon, can grow to about 4' in length and can live over 20 years. Despite its large size this fish is a popular aquarium fish due to its hardiness and very peaceful temperament. Recommended temperatures for this fish are 52-72° F, with a pH level of 7.5-8.0. A tank size of about 300 gallons is also suggested for this large freshwater fish. Like its close relative the Lake Sturgeon (Acipenser fulvescens), the mouth of this fish is actually located on the bottom of the fish. This fish uses its four barbels, located right in front of this strange mouth to find food. The Sterlet can be fed insect larvae, Flake Food, Tubifex Worms and snails. Clean water is a must for this fish and a nice sandy gravel bottom will insure that its sensitive barbels remain intact.
