When all is going well with your tank(s) and your friends are doing well and are happy, isn't that just lovely. To know your hard work and energy has been rewarded. Fishkeeping shouldn't just be about emergencies or deaths or water quality. Fishkeeping should be a pleasure and an enjoyment to behold. It is a wonderful feeling , when someone comes into the room and says to you ,oh the're lovely or that's a lovely tank. You know then all your efforts have been worthwhile. It like the paddling swan scenario. On the surface of the water you see a graceful swan gliding across the water effortlessly, but underneath the legs are paddling like hell. It's the same with fishkeeping. I'm sure you are all familar with that feeling. May you long enjoy fishkeeping.
