Hi Guys (Im new - so hello!)

I have a tank of three fancy goldfish - 1 Black Moor, 1 Calico Fantail and a bronze coloured Oranda!

Ive had them for over a year now, and around 6 months ago the Oranda started to float around on the surface of the tank. I was told to try "Pea Treatment" by starving him for a couple of days then just feeding peas for a week. I did this, and kept feeding peas with normal flakes but it did not help.

It got worse and worse and now for the last month he has sunk! He simply lays at the bottom of the tank, upside down. Its so upsetting. When I feed them, he can just about right himself to eat but I see its getting such a struggle.

Now I have noticed the fantail is floating upside down on the top and the Black Moor is acting very "lazy" by sometimes just laying on the stones and floating around rather then swimming.

We used a reccomended water treatment, they have a tank which I was advised was suitable for the 3 of them. Is there anything I can do? Any water treatments?

I have read that its just a common myth that floating food causes this, but I was advised that in eating the floating food they "gobble" up air!?!
