I can't remember not having fish, i'm 26 now and must have had them for about 24 of those years. There was always a tiny cold water tank with goldfish in in mine and my brothers room when we were young, moved onto ponds and then koi while i was at school. Dug out one of the old small tanks after i finished school and started working away and got some small goldfish again (as well as still having a 5,000gal koi pond at my folks place) then moved onto tropical fish when i saw how large some of them could get and been on those for the last 9 years now. Only really started learning anything useful (and making my wallet much lighter) since finding mfk last year and getting an unhealthy addiction for large catfish, but still not got my fish IQ above 0! my fish teach me something new everyday.
