Hi all. I know little about this species other than what I’m reading here. Have an older sand pit 1.5 acre I’m trying to refurbish the best I can. What are the benefits of these and are they worth trying? I’m just a fan of a bonus fish if they will do ok. How many to try ? I don’t think I have too many lmb to deal with. I hope. So looking at yoy to stock. Help and thanks
