Yes!
A goldfish left in the dark would gradually, over time, turn completely white. This is because the color pigmentation cells responsible for the fish's bright color, cannot work without sunlight. It would, however, take a very long time for a goldfish to lose 100% of its color because they have so many color pigmentation cells in their scales.
It will turn white, or at least will start having some loss of color.
If a goldfish is kept in the dark it will appear lighter in the morning, So if left in the dark for a long period of time, a goldfish will turn almost white. If kept in the light, it will absorb color, and often become a brighter gold. (almost the same as when we tan, the sun gives us color, and when we get less of it we turn whiter, or lighter)
It would die
Yes. A COMMON goldfish is extremely endangered. At most 2,000 left!
If you were an Aboriginal child,and you had LIGHT skin,you were taken away from your parents,and your parents would never see you again. But if you had DARK coloured skin as a child,you would be left with your family. The adults however,were left and rejected from society.
Probably white because of the high silicon dioxide content.
the dark parts
Pakistan's flag consists of a thin white strip (to the left), next to a much thicker dark-green strip. The dark-green part, contains a white star within a crescent.
it would die
Some goldfish, especially large ranchu/lionhead goldfish who are lacking a dorsal fin, may lean slightly to the left when they are sleeping. This is normal behavior and shouldn't be of concern unless the fish is exhibiting signs of illness or is acting lethargic.
Yes but they are also creatures that should be left alone.! :D
