i will be needing to buy some more food for my common and fancy goldfish in the next week or so, and i have no idea what i should be looking for. im in the uk, and at the moment i am feeding tetramin gold japan mini sinking pellets, they seem to be doing well on these but i am wondering if there is anything better out there i can get hold of easily which i made specifically for goldfish, moreso my fancies as i dont want them to end up with balance problems, so sinking food is a must in my opinion. i have looking into new life spectrum and am not sure as its listed for tropicals not goldfish, and ive now looked up mazuri and have absolutely no idea what i would need ot order, in what quantities or how long it would last. any help and opinions more than welcome, thanks.
