Hi. I'm sorry to hear this. I have a few questions that may better help us to help you.

1. How big is your tank?
2. How long has it been setup? Has it completed the nitrogen cycle?
http://www.myaquariumclub.com/the-nitrogen-cycle-for-beginners-358.html
3. What types of fish do you have? How many?
4. How often do you complete partial water changes? How big are they?
5. What equipment do you have setup (heater, filter, air, etc)?
6. Do you test your own water? What are your exact numbers for ammonia, nitrites, and nitrates?

Fish lose color for a lot of reasons. Mostly stress/sickness can cause it. But also different light sources, food intakes, and aging fish can change colors as well.

But answering the questions gloman provided will help us guess what is the most likely cause.

I dont know how it was caused but I do know you can buy food to help your fish keep a good color.

common reasons for a fish losing colour are stress, water conditions and food. N different to a human. My betta really does look better on tetrapro colour. As does everything else in my tank. But know what fish it is would be a good start and the information Gloman asked for.

Please read about the nitrogen cycle. The fish are stressed because of ammonia levels, due to the nitrogen cycle not being performed.

New tanks have to complete a process called the nitrogen cycle. An uncycled tank will stress, sicken, and eventually kill new fish. A working nitrogen cycle is vital to a healthy aquarium. Unfortunately, it is rarely mentioned by petstore employees.

The short version is that ammonia gets into the tank through waste. Ammonia is toxic and deadly to fish. A bacteria grows that converts ammonia to nitrites. Nitrites are more toxic than ammonia, so at this point fish are swimming in two poisons. Eventually, a second bacteria grows converting the nitrites into harmless nitrates. A tank is cycled when ammonia and nitrites consistently test as 0, and nitrates are present but under 40.

Partial water changes are necessary to reduce the toxic buildup of poisons. Change 20-30% of the water every 1-3 days until the tank is cycled. The only way to know when it cycles is to test your own water. Free petstore tests will often give "good" or "safe" as results, but you should have exact numbers as anything over 0 is not safe. When adding water, be sure it is conditioned and temperature matched.

When adding new fish, they should be slowly acclimated to reduce stress. Your fish are most likely suffering from not having been acclimated properly and ammonia/nitrite poisoning. Do 20-30% pwc's every 1-3 days, and test your water daily, until the tank cycles. Depending upon what type of fish you have, they may not survive the cycling process.

10 fish....55 gallon tank....
if one of them are losing it's coulour it can be by
stressed
over stocked
he could be sick or not having enough food
I have a 21L tank and i only have 1 fish left i used to have 3 fishes (all gold fish though) and one died of over stocked (we had fake plants (realy large)) and this could have also died of starvation because we had 3 fish and one of them was dominant (blackmoore) so then he died now our common gold fish is left alone with 2 suckerfish (possible common) and one apple snail....so it could be due of stress

Hi Fish collecter,

Can you please refrain from answering old questions as this pushes new questions down the list, you can find out how old the last post is at the top right of the comments box. Anything over a couple of weeks old is likely sorted unless the op bumps it up again.

Thanks

Hi,

This is exactly what makes many of the forum threads useless. I often find threads which really seems to be going in the right direction, and then, admin locks the topic and there is no more answers.

To answer the question, a 21 liter aquarium is too small for even one goldfish. Because of their short digestive systems, goldfish eat more and produce more waste than other fish their size. That means they need large aquariums.

The ability of the nitrogen cycle to process fish wastes depends primarily on aquarium volume. Thus, a small aquarium just can't provide a healthy environment for goldfish.

I learned that the light in your tank can turn them very light and when you leave it off for a night it can turn them dark.

Big fish, the only reason why it isn't allowed is because the thread is no longer in use and the owner of the thread has gotten the answer they needed. If you have a question about your fish you can start your own thread by asking a question at the top right hand corner in the green box.

Most common reasons for a fish losing color are distress, terrible water conditions and excessive food or wrong food choice.

That's about as readable & understandable as an 5year old writing it! So you had 'fake' large plants that could have died due to overstocking lmfao some retards on this planet

This posting is over 2 years old but regardless of that, there is no reason to be rude.

So I have a fish myself who has originally orange, but four years went by and his scales began to change white... I thought he was dying, but here we are today hes 6 years old has all white scales. I found some things online that said it was because of the source of light I had, but I don't think its going to bother the fish so I didn't really bother doing anything
