I was thinking of setting up a 40 gallon aquaponics setup to experiment with aquaponic vegetable gardening this year. The setup would receive 8 gallon WC's a week and house a sunfish (perhaps a Warmouth? Goldfish are illegal to keep in ponds up here). The sunfish or whatever I get will be fed twice daily. Plants I would like to try include eggplant and lettuce, among others. What are your thoughts on this?
