Fish + black light = bad?

I was considering the possibility of lighting a fish tank with a black light, but was wondering if the UV rays would hurt the fishies. Would it be safe or is it not a good idea?

I think it is safe, it wouldn't hurt the fishies
However it is meant for preventing masses of algae..it is meant for a heavily planted tank. I don't see it doing wrong though.

I already did that...the fish will be ok, its just you gotta have a lot of stuff in the fishtank that glows!! or it wont glow really at all!!! ..hope this helps!!!

I've heard that the fish may go blind if you use a black light. Is there any truth to this?
