Hi, Dinger! I do wish that I had the room for 12 discus. My first attempt with discus began with 12. I do believe that I got 4 breeding pairs from that dirty dozen. I only buy my fish from Kenny. I did too get a fish from him this month. You went shopping. Mind if I ask which 12 fish you chose? My other question is what is a dinger? I can think maybe because you test doorbells? Your are a Mormon missionary. Have fun!
