Thanks for all your help, I think I may get a new fish tank soon and your fish tank is so huge to mine looks nice and your fish do too. We change all of the water so from now on with the advice you gave we will be part water change. also no I do not know how to recycle my tank how do you mean?
The goldfish is a lot better we gave it some swimbladder treatment and he is so much better. Now answers to your questions. Size of out tank is about 12" by 8" and we only have the one fish who is about 6 yeras old. Yes we have a water fliter no we dont test the water how do you do that. We water change it every few weeks I know we should do it more often. And no we dont use a water conditioner.
My Gold fish is bobing upside down on the top of surface, it is still brething. And when put food in its fine eats it than goes back upside down. It does not seem to be able to stay down in the water. can anyone help.
