A friend of mine, a biology professor, has an old friend who has a massive tank and does research on them. I do not know the details, but the tank is BIG, likely many thousands of gallons. I'll have to contact him and get some info, maybe pics.
I tried to buy some from McKencies fish farm but they wouldn't sell to me. Oh wellWont' sell shovelnose sturgeons eitherI can't win for loosing and I have an aquaculture license
