Aquarium Colored Lighting?

the lighting of the bulbs for the fishtanks should not make a difference. really the only time would it matter is if u were using like a black light. i have 3 different tanks. i have two 55 gallon tanks and a 20 gallon tank. they all have different color lights. i have fish in each tank that have been alive for more than a year. it all depends on how you care for your fish (cleaning,watercare,food) the lighs wont make a difference.

i think it is not my fish have blue lights and there fine
