Hi everyone, Is it possible to use tropical fish in an aquaponics system? I'm thinking about purchasing a Water Garden (https://backtotheroots.com/products/watergarden) and would like to fill the tank with a tropical fish, but do not know the effect on the marriage between the fish and plant. Do the fluctuating ammonium and nitrate levels effect tropical fish more or less? Let me know when anyone gets a chance! Thank you kindly!
