mine is pretty boring, my dad had a 6ft tank for about 2 years when I was little, yet I was the one who looked after it (probably not very successfully, but don't remember very well), i was about 6 when he got it.
WE have always had gold fish and shabumpkins.
When I moved out dad had been given a tank , but decided to up grade so I had it about 6 months later (3ft) fillrd it with various community fish.
Came home from a weekend away to find 40 odd guppy fry, so got a 2 ft sharpish for them, and started to breed properly, then babe, no 2 came, so i gave all the guppies away, apart from a few gorgeous males that were the offspring. And filled the 2ft with more community fish. That was about 4 years ago.
I now have a 35 gallon tank with the community fish and a little tank for pig the fantail and fred the last guppy. I have had a very happy 6 years with my own fish
