F is for Fish!
When I was a Sophomore in High School I started breeding Betta Fish. These are also known as Siamese Fighting Fish & are commonly seen in those little bowls above the fish tanks at pet stores. Unlike gold fish which actually need a big tank & lots of filtration, bettas can really live in a little bowl. In the wild they often slither between muddy water buffalo footprints.
Honestly they are just really pretty fish & enjoyed my little row of tanks across my desk.
Eventually my love of bettas lead to a job at our local mom & pop pet store. I really loved working there. I guess fish have always fascinated me. I was also so surprised at how colorful & interesting fresh water fish can be. My favorites came to be a family of fish called Rainbows, they're mostly from Australia & New Zealand. When the males court the females they flash colors down their side, turn a stripe that runs between their eyes bright yellow, and do amazing displays of their finnage. I could (and often did) watch them for hours.
