Answer
Hi Anthony;

That sounds pretty bad I'm afraid. Once they start acting like that they don't usually make it. It would be best not to get another one though. Fish stores should not sell them for home aquariums because they actually need lakes and large ponds as they grow, and they can grow very fast. It's very possible your fish store doesn't know enough about them to realize that. You might want to let them know.

Sturgeon are also a cool water species and will not do well in a tank over 74f. They actually prefer it in the 60's or lower. Here is more info about them;
