Would anyone recommend any?

green algae.

Bloodworms

i don't think there is a specialize color enhanced food... just normal color enhancement pellet food will do ?

I've heard spirulina is great.

Have anyone tried color bits? I've used them on my tropical fish and with a good result. Not sure it would work on GF.

How would green algae enhanced the red color? It makes sense if it enhances the green color if there is any GF in green color.

I remember there was this huge oranda with intense red color in my LFS the other day. The color started to fade after a week in the store. Then the fish was gone. I was wondering what type of food the breeder was feeding him and makes the red color so intense.

I even heard some of the fish were being injected color... Not sure anyone heard of that??...

If you want nice bright colors..how about getting a pond? Nothing better than natural sunlight

Really? Sunlight enhances the color of the fish?

So leaving my flourcense light on 10 hours a day might help enhance the color since the light was made for a planted tank.

well high voltage light will keep your fish black color...but i don't about other fish colors..

I believe varied foods is the best way... make sure there's a rotation. I feed mine Hikari, frozen mix, peas, rice, corn, eggyolk and lettuce sometimes. Will try cucumber and beans

I noticed a difference in color when I opened my curtains and let the sun in on a regular basis. I was in California so I got alot of sunlight! Also, I fed my fish Progold and Spirulina flakes, and supplemented with frozen Krill on occassion... It appeared their reds deepend. I used to call my Lionhead a "lightbulb" he was so brightly colored.

Sunlight is, indeed, one of the best ways to bring out the intense colors of your fish. Flourecent lights will not do the trick. A "full" spectrum light is better than nothing, but is pale in comparison to full sunlight.

I take my best show fish out for a few weeks prior to a show - and their colors really brighten. WHites pop, blacks deepen, and reds become intense.

Feeding spiriliana does indeed do nice things for the color, as does shrimp. I have shrimp pellets from GC as well as shrimp in other forms. Just as the pink/red of shrimp colors the bright pink/orange feathers of the flamingo that eats them, the goldfish, also, will begin to show reds and oranges much better with shrimp. The main problem with shrimp is that the whites on the fish may become "pinkish" - and not bright white or well defined. For this reason I stick to the shrimp for color on a fish that is mostly red.

Desiree,

Those fish in the pics attached in your post look amazing. I like their color, they are so intense. I wish my fish are all have the color like that.

I get no sunlight into my room, sigh..

As well as all the truth above on food variety and sunlight, strong deep colors on fish indicate a healthy, strong immune system. The very slightest damage to tissue or nerve cells and any "healing" anywhere causes a subtle change in color pigmentation- a dimming. Color maintenance as an extremity is one of the first things that goes when a fish is under parr (rather like our hair might get oily or dry when we have a cold). So keeping fish disease free and tank conditions tiptop as well as feeding plenty of varied nutritious foods plays a part in color vibrancy too.

Fish also display their most brilliant colors when they are in peak breeding mode.

mmmh. That explains why my sarassa comet is getting really bright red and her white belly and chin are slowly turning light orange. If she continues to change colors she'll look completely different.

Thanks! What kind of light do you have? I just bought a T-5 at the suggestion of the guy at my LFS... he is really knowledgeable (even about GF!) and he said this type of light is good for bringing out colors in GF.

You have the T-5 MH light on your GF tank? I think those for reef tanks..They consumes a lot of electricity. I have the regular flourscent light that supposed to be on a 10G. Now I'm using it on my 30g tank.

I have been feeding this for the past several weeks:

It seems to be making a difference -- my formerly all-white lemonhead oranda is actually taking on some calico coloration and the intensity of the orange and red in my other fish is greater.

You'd better stop feeding them that stuff fast!!! Those white goldies are my faaaaavorites and so rare.

I know. Betsy's tummy is now almost all light orange and she is getting an orange scale here and there on her body. I am not sure what to think -- was she white when I got her because she was being fed a deficient diet at LFS or is all just because I am feeding color-enhancing food? My other fish are really benefiting from the food, however.

Part of the problem is that Betsy tends to take more than her share at any meal. She has one of those big Hoover mouths and she ends up with probably 2/3 of what's served (whether I try to feed at opposite ends of the tank or not!)

Bloodworms are a good food for this, and also add a nice "glow" to the scales.
Adding foods high in carotene to gel food, or feeding them as a treat will also do, such as carrots and red peppers.

As a reply to 32Bit's post on the previous page, artificially colouring fish is quite common, but more so in tropicals (from my understanding). That way, colours that appear almost unnatural can be produced. The colour can be injected under the skin, which is strssful for the fish. Another way of colouring the fish would be placing the fry in dyed water. As the fry grow, they absorb the colour and are kept in the water until their colour appears solid. An example of this would be the "Gold Skirt Tetra", and is sometimes known as the "Black Skirt Tetra" or "White Skirt Tetra" (most commonly comes in pink, purple, green, or blue with orange highlights).

I heard fish that were injected with colors or artificially color enhanced will not grow to its full potential size. Is this true?
