🐊 Diamondback Sturgeon (10–12”) – Ancient Coldwater Swimmer with Prehistoric Appeal
The Diamondback Sturgeon (Acipenser fulvescens or related hybrid species) is a majestic coldwater predator known for its armored, diamond-shaped scutes, torpedo-like body, and graceful, bottom-gliding movement. At 10–12 inches, this juvenile is well established and actively feeding—making it the perfect size to introduce into a large coldwater tank or koi pond.
A living fossil dating back over 200 million years, the Diamondback Sturgeon offers rare visual beauty, peaceful behavior, and interactive intelligence—often hand-feeding and recognizing its keeper over time.
