new light

[fish_freak]

I just got a new coralife color glo light for my 90 gal. The old light was just a standred flourescant that came with it. Any one know it these lights acctualy make the fish more colorful like they clame?
I can tell that the light makes there present colors brighter but I am wondering if it will make them more colorful fish due to special spectrums or something like that.

Coral life bulbs does make good lights. I have a 50/50 bulb form my 60 gallon tank that i LOVE and is working with 16 hours days times one year so far and still working.

They do make several types of brands. One may work to bring out the colors, another one for your plants, another one for coral. So each one has a different ability. You would have to compare them to see which is best for your likes.

There are some bulbs that bring better colors out... But it usually is better in Saltwater, for some odd reason... What kind of fish do you own?

Are you asking if certain lights will physically change your fishes colors? Or are you just talking about how the fish appear under a certain light?

If it will phisicly change there colors. It claims it will.

it shouldnt. well not permanetly anyway.

some fish may show brighter more intense colors under lighter or darker conditions.

I agree. There is no way a Light can actually change a fishes color. The colors may seem bolder or brighter when you view them though.

Actually i correct that. Maybe in a LARGE tank (1000 gallons) with predator fish and using ONE type of light for several THOUSAND YEARS (maybe longer) the fish that are the prey will change their colors to blend in with the environment to escape the predator. You cant be bright yellow with a predator after you....

I suspect that the Coralife people meant that their lights enhance and clarify the natural colors of fish by providing a more complete spectrum.

Light levels can also alter the color of fish. Some might display more intensely, some may be stressed by it and wash out.

As for evolutionary type adjustments, they can happen rapidly provided there is some selective pressure. There is a smallish section in the Beak of the Finch that describes some experiments John Endler did with guppies, and colors and patterns changed (were selected for) in just a few generations. Thousands of years are not needed.
