Default Does changing light bulb color affect fish?

Hi FishForums. I needed an answer to this question, and was hoping somebody here could give me a quick answer. I have a 29 gallon freshwater tank with a bunch of assorted Tetras, Silver Dollars, nothing too exciting. These fish have been under an Aqua-Glo light bulb for many many years, and today I went out and bought my annual replacement bulb. When I got home, I noticed that the label on the bulb wasn't my usual Aqua-Glo, rather an Eclipse Daylight bulb. I plugged it in, and I liked the color it produced, so I was planning on keeping it. I was simply wondering whether this change in light intensity and color will affect the fish, and if I should go return the bulb and get my 'old-faithful' type. Thanks for your help in advance!

if we ignore nature;maybe it will go away

10 gallon..nothing but air

10 gallon...just more air

The only thing it will really change is the coloring in the fish. Some look more colorful or less colorful in different lights. I have a light that really brings out the red coloration in my Cherry Barbs. It does not physically make them change, it is just how the colors are perceived.

20 Long: 1 Juli Corycat, 4 red line tetra's, 3 Von Rio tetra, 1 Flame tetra 1 Rubber lipped pleco, 1 Curviceps cichlid, 1 blue tetra.

5.5ga- 1 Beautiful Betta, 1 persnickety snail

I have green things with leafs.

Note's from Bradley: "Meow." "Yes I did say meow, and I meant it."

Note from Kiera: "Can I Play with it? Can I play with it? Can I play with it? Please? Please? Please?"

some fish will act shy in brighter light. Mostly they don't care. Plants care, fish don't.
