What Types of Fish Have You Owned?

Over the years I have kept most types of tropical, marine and coldwater fish. I opened my own fish hobbyist shop back in 1983 and although leased it out in 1993 due to the recession only sold it in 2001 when we sold everything up and relocated to Tenerife.
Although as with everything technology moves on and improves the basics of good fishkeeping be it tropical, coldwater or marine remains the same. The biggest advances probably having been made in marine fishkeeping. Something that was very much in it's infancy in the days when I started.
