When we were kids my sister had a small 10 gallon tank with a few fish in it. (Don't remember the types, sorry.) We didn't know a thing about what we were doing at the time and I'm sorry to say that all the fish eventually died and the tank ended up upside down as a small "bench" in my sister's bedroom.
Anyway, when I was 8 or 9 I think, I was sitting on this "bench" talking to my sister when the "bench" cracked and then gave way!! I fell through to the floor! (Mom was at work at the time and dad was out in the barn doing chores...) After we all stopped laughing hysterically, my sister pulled me up and I finally noticed the blood and comparatively large piece of glass stuck in the inside of my upper thigh. (Barely missed something vital to us guys)
I hobbled myself to the bathroom were my sister (About 10 years old) helped me pull out the glass and put a small bandage on. It bled for quite a while though and we had to change the bandage a couple of times. (Note that we knew nothing about anatomy) Fortunately for me the glass had missed the artery. When mom came home she of course freaked out when we told her and drug my embarrassed butt to the emergency room!!
The doctors and nurses had a good poke around down there looking for any more damage. Not finding any, they simply taped the wound up and sent me home. I still have that scar to this day... but don't ask for pics!!
Anyway having grown up and moved away from home I got interested in fishkeeping again and made another attempt to start up in the hobby. (about 19 to 20 years old at the time) I finally got a tank of Tiger barbs, Tetras, and Cories going in my apartment. Anyway the Tigers and Tetras didn't get along too well. Tank was probably too small and again I didn't know much about fishkeeping. The kids at the Petsmart and Petco of course gave me mostly crappy advice. So the attempt eventually died and I gave the surviving fish back to the store.
Now I'm 30 something and my wife wants to have a go at fishkeeping. Besides, I really haven't ever lost my interest, so here I go again. This time it seems I've found a TON of forums, info and friends I never really had to draw on before, so I may actually succeed in this third attempt thanks to the internet and all of my forum friends.
