ok, so I decided not to turn the frog tank into an aquaponics system. It's going to be too difficult. So I scaled back even more. Just a regular tank you can purchase new for $20, and air pump ($10), and a bag of cheap goldfish ($5). I will later pump the fish water to a plant bed.
Goldfish are good because: 1) they are cheap, 2) extremely hardy fish, 3) will eat anything. This keeps my costs and problems to a minimal. The frogs environment will not change at the moment.
tried feeding them a piece of cooked polenta and they appear to be enjoying it.
