I see you posting about your FHs all over the place . . . I think you need to slow down (I know they're both dead now) . . . first off, I don't think Deep Blue said the light killed your fish, he just suggested you turn off ANY lights in the tank while your fish was ill
you described a "UV" light that is 2x96W . . . that doesn't sound right; are you just talking about your normal tank lighting? 2x96W sounds like typical compact flourescent (CF) lighting
you didn't say anything about your water parameters, and it sounds like you didn't cycle your tank . . . I think that is the source of your problems
my advice, again, is to start over and go slooow . . . sorry for the loss of your fish, I now how much that sux
