fish death due to lighting?

[b.crabby]

i had what the lfs calls a scooter blennie(which turns out to be not a blennie but a fish in the manderin family call a dragonet, or somthing like that).anyway, i had this fish for about a year or so and it did very well in my 90 gal reef intil i installed my new dual 400w 6500k mh system. for the first few days it hid from the lights and after about a week it disappeared entirely. i can only assume that he is hermit food by now. i had never heard of fish who had died from lights. any thoughts?

Unfortunately, scooters (like mandarins) often die of starvation in our tanks. And often, this starvation takes 3-12 months (can take them that long to gradually reduce the pod and microcrustacean population to a level where they don't get enough to eat).

I can't think of any reason for the lights to kill the fish directly (even with a drastic change in lighting, in an established system that shouldn't stress the fish to death), so it may just have been coincidental timing (or perhaps the stress of new lighting on top of lowered resistence due to incipient starvation).
