I have several different fish in mine. Crappie,3 koi, catfish, bass, perch, 2 grass carp. It was only about alil smaller than an a 1/2ac. Just finished digging it out. Now it should be around 3/4ac. I would love 2 add some HSB in my bow. The fish truck that comes to town doesn't have them. I havnt really looked into getting them somewhere else.
