A few days ago, on a whim, I decided that I wanted a fish. Mostly because I'm lonely and pathetic, and because I really like fish.
I got a goldfish, (yes a goldfish) and at the time I didn't know really what I had gotten myself into. The reason I picked this specific goldfish is because he was all alone in the tank, so maybe he was just as lonely and pathetic as I was.
He didn't seem to be sick (Most pet stores take other fish out of the tank, where one is sick so to protect them from getting whatever disease the sick fish has.) he was swimming around with a lot of enthusiasm. Which raises a lot of questions about why he was alone, like "Did they sell all the other fish in that tank?" "Was he aggressive toward other fish?"
"Did he eat all the other fish in the tank?"
"Is he like Christian Bale in that American Psycho film? Did he go after the other fish with a chainsaw?"
All questions that didn't occur to me until after I had purchased him.

After getting the fish home and researching. Because lets face it goldfish die supposedly very fast. And I had already bonded with my pathetically lonely friend and wanted him to live forever and ever and never die. I needed to know how to keep him alive, and since they don't give out pamphlets on "How to keep one's goldfish alive" I searched the inter-webs for answers.
I found out that goldfish absolutely must have an air pump, if you want them to live any length of time, which I didn't have. So I had to purchase an air pump, a new tank, a bag of rocks, and a tank accessory in the form of a whale with a gaping mouth for Garfunkel (my fishes name. At first I planned to call him Achilles and then I remembered that Achilles died very young and that felt like a curse.) to go into and a hole in the stomach for him to come out of. Having to wait to get the air pump and for the water to filter I had to keep a close watch on Garfunkel and make sure he was still alive and change the water he was in frequently. It was very stressful for me and Garfunkel and wouldn't have been, had I been prepared.
Here's my advice.
1- Don't buy goldfish on a whim.
2- Make sure you research different types of fish before you decide to purchase one.
3- Don't name your fish Achilles.
