Hi again, I bought the API salt and changed some of the tank water...I used the gravel cleaner first of all but he kept swimming over to it to investigate and I was petrified I was going to bash him with it, cant say I was that impressed unless Im doing something wrong. I measured it all up correctly the tap safe and the API. I also bought him some goldfish sticks to eat instead of the flakes. I put two wee sticks in his tank but they just floated on the top and he was taking massive big gulps trying to swallow them , he would get them in his mouth but than let go off them so he ended up not eating them I took them out and put his flakes back in.. Looking at him today his skin looks painful I didnt use the white spot treatment because you told me not to. I hope the salt will help him. I went to my local Garden nursery where I had actually brought him from all those years ago They have a pet place in there and got talking to a lady about my goldfish. She said if I want to rehome him I can take him back to the nursery and they will find a good home for him as they do rehome fish. I have decided this is what im going to do but I have to get him healthy first she said. She was showing me the size of the tank that I would need for him and its just massive I have nowhere to put a tank that size in my sons room or even in my lounge so this is the best decision for him. I hope I can make him look better and as soon as he is I will take him to her. Thankyou again for all the help you are giving me. I did water test and everything still looks high its a strip test My one from Amazon arrived today too. The NO test looked ok..The KH one was high so was everything else...I dont know what any of the stuff on there stands for. Im totally confused and worried im going to make him more ill.
