<human>: Give me a shortened version of the text

This happened in high school. I had an after school job at a local pet store in our mall. It was an awesome job. Do the chores and you get to spend the rest of the time standing at the front of the store with a puppy talking to girls. Every Wednesday we would get a shipment of fish, all kinds from tropical to the common goldfish. We would always get a large amount of goldfish because parents would buy them for kids or more commonly, people would buy them to feed to their [Oscars] or Piranhas. I noticed that a couple tanks had some [Ich] in them. I grabbed a blue bottle that we use to treat the fish and the tanks that have Ich. A little goes a long a way and the stuff is not cheap. I treat all the tanks and get to the last one on the bottom that had all the goldfish. I start pouring in a the bottle and it slips and the whole thing goes in. I quickly grabbed it and took it out but half the bottle was now in the tank. This is not the FU. The chemical is not deadly to the fish and they would have been fine. The problem was it dyes the water blue, and this much chemicals dyed the water to color of blueberry juice. In a panic that I would get in trouble I had to think of a fast way to fix the problem. Then it hit me. Bleach. So I get the bleach in the back that we used to disinfect the pet cages and add just a drop. It worked! Like a reverse cloud the blue color began to dissipate. I added a couple more drops and walked away in awe of my own brilliance. I went about my other duties and walked by the fish and that is when I saw 300 gold fish belly up.
<bot>: I overused a blue chemical to treat a tank of goldfish with Ich. I used a bit of bleach to remove the color. Mass murder was the result.
