Recovering from a crash myself. Went out of town for the weekend, and my GF came by to do some housecleaning and feed my fish. I told her to make absolutely sure her hands were clean and very well rinsed before feeding the fish. She won't fess up to it, but, I suspect that she had some bleach or pine-sol, or something on her hands when she fed my fish. I returned to a deat trigger, 2 dead tangs, dead blenny, dead cleaner wrasse, and two dying clownfish.
Can't get too mad at her. She was trying to help out while I was at a computer bootcamp. She won't fess up to it, but, she did say that she'll never touch it again. Ever fealt releived, pissed, confused, but sympathetic at the same time? LOL...
