How do I select a good fish?

Check that all the fish in the tank look clean and that their fins are not torn or that any have white spots on them.  The fish’s skin should look bright and shiny, and their eyes clear.  The tank itself needs to be clean and the water must be clear.

Do not buy a fish if there are any dead fish in the tank.  All the fish should be moving around the tank not sitting on the bottom or floating on the surface of the water.

It is best to buy goldfish when they are still quite small ie no bigger that 8cm (3in) long.
