fish sight....

[reefiness]

my friend came over today and looked at my tank and he loved it

e.... i answered all of his questions except for 1 which i need help with... he asked
"what do fish see, like you know how dogs see in black and white, well do you know if fish see in black and white too or do they see normal colors"

so i forward this question to you experts out there....

WHAT COLOR DO FISH SEE IN??? :thinking: :thinking: :thinking:

well incase anyone was wondering i found it out myself fish can see in color. Fish eyes contains about 125 million "rod" cells which distinguish between light and dark and close to 6 million "cone" cells which distinguish colours. Each cone cell contains a visual pigment which absorbs light of a particular wavelength, generally between 400 and 700 nanometres (nm); the range of visible light.

WOW, great info..is this limited to certain fish or can the all see in color?

all fish can see in color... although the amount of cells in their eyes change with age and species...
theyre are 2 types of fish which can also see uv 300-400nm that is the "japanseese dance fish" and the common goldfish.
