Hi guys, I've been looking into buying a single diamond sturgeon for quite a while now and I would like to hear an outside opinion. If bought, it will be around 5 inches or less from a local (and trusted) retailer. My problem is the size. I have a 100 gallon tank, and a stocked and well-kept pond behind my house roughly 2 acres in diameter (give or take). I wish to keep it in a tank until it is large enough to play with the big boys. Comments? Suggestions? Any prior experience would be GREATLY appreciated before I take the plunge. I do have experience with larger fish, with about 5 six year old koi, as well as full grown pleco's if that helps.
