I never owned a fish longer than it took to get it into a skillet until 16 months ago when I started a little indoor aquaponic system. It wasn't the original idea but I ended up with two Fancy Goldfish, Sara and Maybelle, who, to my surprise, have become beloved pets. I recently wrote about them here
so won't duplicate all that. But learning enough to keep them happy and healthy led to several aquarist and fishkeeping forums. I don't fit in too well there though because I'm not a collector of fish. If the two I've got now live a full life I'll likely be too old to get another. And my interest in the
aquarium is primarily as one piece of the larger aquaponic ecosystem.
