Goldfish see in color.
umm... oh, the goldfish is orange, as you can see.
It depends on what kind of goldfish; normally, you just have to wait to see who lays the eggs to find out the sex of your fish.
Different types of goldfish food typically don't affect the colour of goldfish, however there are some specific goldfish foods that may enhance the color of goldfish- but do not change its overall color.
I think so but I most likely see them gold.
No they are not.
Yes, a goldfish can see you; in color for that matter. Goldfish have eyes on the sides of their heads which gives them a blind spot right in front of them. They can see fairly decent close up but not as clear at greater distances. They can also sense your movements with their 'sixth sense' located in their lateral line. It helps them recognize where predators are approaching from.
goldfish are not always one color because they have different species. Also, goldfish can change colors over time. They won't always be gold or maybe they won't always be white or whatever color your goldfish is.
Goldfish are not colorblind but they have very sensitive eyes and the can only see four different types of eyesight which are:ultraviolet,short,medium,and long wavelength-sensitive.
Grey is the natural colour of the carp the goldfish was developed from.
Goldfish can lose their orange color due to light deficiency or dietary deficiencies. In these cases, the color change is often reversible.
