uhhh...i have read in several places blacklights and fish are a very bad idea, as well as anything that can create un natural lighting affects (strobes, odd collored or flashing bulbs,ect).
one thing I have done on my tanks in the past is run a lower watt light set up for a moonlight affect at early night and seperate lighting for the daytime.
you want lights out on the fishtank for several hours to simulate their natural enviroment and ensure a stress free tank.
with that being said, you could build a custom hood that uses the swirl style flourescent bulbs pictured in this post and then using, say, a 4w blue night light bulb or several depending on the size of the tank to give the tank a moonlight affect. have a timer for running the normal hoodlights untill dusk, and from dusk till a few hours after night fall have a seperate timer running to your other lower watt fixture.
i found a one or two 4watt blue bulbs give off a nice gentle glow in my 29 gallon tank. at night my corys and south american bumblebee catfish(he only comes out in the dark) dont mind at all, and the other fish just sleep through it.
