I have a 90 gallon planted tank with 2.4 Watts/gallon T5HO lights. I need to restrict the photo period to about 8-9 hours due to algae issues. My pressurized CO2 comes on and off with these lights. When these lights are off, the tank looks very dark and the fish are not really visible.

I would like to add lights that make the fish look good but will not cause any significant plant (or algae) growth. These lights will come ON when my T5HO turns OFF. Do such lights exist?

If your lights are in a hood maybe you can get one of the cheap LED strips that you can install inside.

My lights ARE in a hood. They also include 4 "moonlight" LEDs ... are you talking about these (not very bright) or different ones?

Thanks!

Could go with something like this? http://www.fosterandsmithaquatics.com/product/prod_display.cfm?pcatid=19788 Replace any airstone you have with it and provides in tank lighting. I have one of those in blue that I use for moonlight lighting and don't even use the bubble part anymore but it works either way, in or out of the water.

I guess I was looking to buy a second set of lights that go above my tank (I have lots of room) ... just did not know what kind ...

My T5HO hood has 4 bulbs with 2 separate controls. Maybe I can replace 2 of the bulbs with "fish viewing" bulbs that stay on longer?
