Step 1
Remember, many goldfish naturally change colors. Goldfish seem to change the most color in the first two years of their lives. If you want a goldfish that won't change color a great deal, try to buy more mature goldfish. However, younger goldfish are often the brighter than older goldfish.
-
Step 2
Feed your goldfish special food, designed to enhance their colors. These foods contain special planktons and carotenes, lycopenes that make the color of goldfish look brighter.
-
Step 3
Keep the aquarium clean. An aquarium full of algae and dirty water will make your fish unhealthy and keep their colors from being as bright as possible. Get rid of any algae, perhaps with an algae eater, use filters and change the filters at times to keep the aquarium as clean as possible.

Step 4
Place your goldfish in a sunny outdoor pond. The UVA and UVB rays will help bring out their colors. If you want to make your fish turn pale, put their aquarium into a dark room.
-
Step 5
Think about feeding your goldfish natural ingredients such as worms and insects. This is easy if you put them into an outdoor pond.

Step 6
Consider that black colors on goldfish may be from bumps that are healing. You may notice these in new goldfish introduced to your aquarium. Usually these fade within a few weeks with no treatment from you.

on 5/2/2008 NEVER put an alge eater in to a tank with goldfish. When the goldfish fall asleep and sink to the bottom of the tank many alge eaters will snack on the poor goldies slime coat which can lead to infection and illness.
