Sorry to hear this
what kinda powerhead was it?
SAD sad day Dec 31, 2009 (loss of 1 of my naked clowns)
warning to all if you have powerheads in your tank please check them when you turn them off. I had an incident yesterday where during a water change, powerheads turned off, when everything was turned back on took notice to one of my naked clowns was in the powerhead.
I am now saving for the seaswirls to get rid of all powerheads. Sad thing is this is the second fish this happen to the first was a bluespot jawfish, this time wasnt myself but my room mate so she is very upset.
I went to a fellow reefer's house Wed night and he uses seaswirls, he doesnt like powerheads at all. They are pricey but after investigation they are so worth it. Marine Depot sells them amoung others. Check them out.
Koralia #3, I almost went out and bought another naked clown but thought against it. I am going to wait until I build up the funds to buy the seaswirls. I really bad for my room mate she is taking it hard because the same happen to me two months ago with the jawfish. 
sorry about your loss. i had a yellow tang grazing by the intake of a power head with out a guard and he got his eye sucked out of his head. learned my lesson there.
sorry about your loss.......i know how much it hurts....I got back home on Christmas day only to find that my electrical strip shorted out and my tank didnt have oxygen for over a day....needless to say, almost everything died.....my sixline wrasse, my domino damsel, my yellow tang, my flame angel, my 2 blood shrimps, my 2 skunk shrimp, my 2 camel shrimp, 2 out of my 4 peppermint shrimp, and a few others that were swimming around im sure.....it was heartbreaking to say the least.......I wanted to throw my tank out the window and quit but thanks to this community, I decided to stick it out and learn from my mistakes....I am getting a UPS to put on the tank as soon as the cash scares itself up...lol....
i havent had any problems with powerheads to be honest, I have the maxiets and they have a cover on the bottom and it keeps stuff from getting in.......even shrimp have gotten right on it but they are strong enough to get off......i have the biggest size too....the mj 1200....
I have one M/J 1200 and i love it
I feel all your pain i screwed up and my midas blenny backed up into my powerhead and got chewed one day i was mad
