As I'm sitting here in bed watching pinkie the convict in his tank, I realised its the same slightly-larger-than-2' tank I set up as my very first tropical tank. I was given the tank by a pommy guy who worked in the orchid next door to my parents when I was 11 (1992). I had goldfish, but he knew I wanted tropicals and a bigger tank (it seemed HUGE at the time). He made it himself!
I didn't set it up for a few years, and when I did I had an eclectic mix of community fish, which mostly got destroyed by Arthur the firemouth. That lasted about 8 months before I bought a 4'er. Since then its spent many years sitting empty under the house, occasionally being pully out of retirement for all sorts of things; raising convict fry, seperating aggressive cichlids, planted community tank in mum's classroom, a group of small electric yellows, two different large male convicts (at seperate times), even keeping native skinks!
So, do you still have your first tank?
