You'd better hope so for size reasons!
I actually work at a sturgeon farm. We raise Siberian sturgeon, Russian sturgeon, and besters. They eat pretty much anything. We feed ours sinking pellets but they can be trained to take floating pellets too. Our Siberians grow a little more than a foot per year. We don't let the water go above 75 degrees at any point, and below 65 or so is optimal. We start the babies off at 50 degrees, and adults are even happier in the 40's. Unfortunately, in Florida that means a lot of money is spent running chillers.
