I'm so mad at myself right now. I have a couple of tanks right now. One's a 55 gallon with goldfish and the other is a 30 with tropicals. Well anyway, I'm, doing my bi-weekly water change, I usually do a 50% on the goldies and a 20% on my tropical. While I'm doing my 55, I break my StressCoat (dechlorinator with aloe) bottle top. So I finish up my 55 and put a little sxtra Stresscoat in the tank.

I go over to my 30 that has my tropicals in it. Its a well established tank. It has 2 veyr large angels (I've had 1 for 3 years now and the other for 2) and my favorite fish in the world, Old Red Ass. He's a redtail shark that I have had since I first cycled this tank. I also have an albino clawed frog, 4 serpea tetras, and 3 clown loaches. Its a great tank with lots of live plants like Java fern and moss. So I have all this extra Stress Coat and when I put in my fresh water I over treat it.

The fish seemed fine that night (I had gone out and got a little baby angel to replace another large one I lost a week ago, the one I lost I had for 2 years). This morning before work, Old Red Ass is boobs up floating while my Angels look like stir fried poop. I could have killed myself. I got home after work and did a 50% water change just hoping and praying i don't lose my loaches or my new baby angel.

So has something like this ever happened to you? Have you destroyed a self contained enviroment that you were responsible for? I've lost many fish in my lifetime (I was a pet store manager before I left for the military and I use to work in a fresh and saltwater wholeseller in Atlanta) but this one hurt the most.
