Great minds think alike, I see. We have a 24 ft., 42 inch deep above ground pool that my husband is stocking right now from fish that he's caught in the river. He added 4 lbs. of minnows a couple months ago. Honestly, while I NEVER see the fish near the surface, I've seen only one dead minnow. This past week, he started adding larger fish from the Spring River, here in northern Arkansas.
You will have to try to keep leaves and other organic material out of the pool because of the tannic acid it releases into the water. We will also be adding a pump to help keep the water aereated (sp) and some type of filter syster.
Last year we failed to put a winter cover over the pool, we only had a mesh leaf cover. OMG......we raised MILLIONS of tree frogs in our pool!!! The noise was deafening!! People tease me about our Frog Farm!! :haha:

BUT I can't say that we failed in providing the frogs with a breeding area.

And there is no shortage of frogs around my house. Besides, they help to keep the mosquitoes under control.
I really do need to float some kind of plants on the surface for oxygen manufacture and cover for the fish.
Good LUCK!!
