i have two 2" grass pickerel (almost too small to photo) and a 5" sterlet
i know i will get ripped for the sturgeon, but he has a pond waiting for him when he gets larger
man I want a pickerel, wish we had them natively around here. Northern Pike/Muskie is all we have locally both of which grow WAY too quick (for my 175 anyhow)
for sturgeon just make sure your its got a good strong well over rated air pump n stone and it should do great... people worry far too much about temps... its lack of air 90% of the problems with sturgeon...
lol beluga's can get 19' live 120yrs.... most dont get that big luckily.... yeah 6' is a wild average for most sturgeon, some stay smaller but most get huge...
