A goldfishes colour does not help it survive. The goldfish is a man developed (through selective breeding) species and did not evolve naturally. When they are released in the wild, they breed and the brighter coloured ones get eaten more readily because they are relatively easy to see. This eventually (over the years) makes the species slowly return to their original colouring which is a drab green/brown on the back with a silvery belly.

The colour helps it blend into their environment.
It helps them blend them and be hidden from predators (That is if the them is not at the top of the food chain. otherwise its useless)
Color effects survival of prey because it allows the prey to hide in the environment or to scare away predators. This can help the prey to survive.
