I've just asked all of mine and they ganged up and said "Mind your own business - it's nothing to do with you whether or not we can see in colour, and so what if we can - what good is that to YOU" - so I gave it up as a bad job!

Visual cells of bony fishes, which include goldfish, include rods and cones. Cones are adapted to detect colors, and function well in bright light; rods are more sensitive, but do not detect color well, being adapted for low light. Certain visual cells are specialized to particular wavelengths and intensities. Goldfish have rods and cones that can see four different wavelengths of light (which we call color): red, green, blue, and ultraviolet.The eyes of a goldfish are so sensitive, they can see the infrared beams that control our televisions and videos, so be careful and don't aim the clicker at the fish tank!

The goldfish is not color-blind. It is a tetrachromat.
A number of studies have investigated the range of color discrimination of this animal. Generally, it seems that it can discriminate between a wide range of wavelengths, including ultraviolet.
Light Spectrum Wavelength in Angstroms Light Wavelength in Millimicrons
1,000 to 4,000 Ultraviolet 100 to 400
4,000 to 4,550 Violet 400 to 455
4,550 to 4,800 Blue 455 to 480
4,800 to 5,000 Blue-Green 480 to 500
5,000 to 5,500 Green 500 to 550
5,500 to 6,000 Yellow 550 to 600
6,000 to 6,500 Orange 600 to 650
6,500 to 7,000 Red 650 to 700
7,000 to 100,000 Infrared 700 to 10,000
In that sense, it is tetrachromatic because its color vision is based on four types of cones (ultraviolet, short, medium and long wavelength-sensitive). However, the actual range of wavelength discrimination highly depend on the (white) light level of the room. When the lights are diminished, discrimination between mid and long wavelengths (associated to a green-red discrimination) is non existent. In such conditions, the long wavelength sensitive cones have little contribution to color perception in the goldfish. So, in the right light, they can see a variety of ultraviolet colors.
Hope this helps you !

Yes they see color.
I don't believe scientists have discovered any animal whose eyes don't have rods and cones together. That means they've yet to discover an animal who is colorblind.

they can't because their memory only lasts 3 seconds.

i saw a show on television and it said fish are color blind
