yeah- I am going to let the plants grow a bit taller first before I raise the water level. Once I raise the water level I am going to try putting one small minnow in there. If it doesn't jump out for a week or so I will add 2-3 more, and keep adding until I feel the stocking level is reaching its limits- and I get the feeling that that will be at about 4-5 small minnows.
