I have a Chihuahua/dachshund mix named Roxie. She looks like a black dachshund with longer legs and a longer tail. I've had her for around six years.
I also have a fish, who's orange. His name is Ronathan. When I first got him, he was part of a science project that dealed with how they survived when we gave them different amounts of food and tank water. I got the first fish for our group. He was bright red, small and a spazz. His colors reminded us of Ron Weasley's hair and this guy in our group with naturally bright red hair called Jonathan. So we combined the names and came up with Ronathan. We had two other fish: Candy Corn and Chubby. Candy Corn died for unknown reasons. So Alicia (A girl in my group) and I got to take the fish home. About a month later, Alicia reported that one of her bigger fish ate Chubby. I've had Ronathan for around a year. Over the months, he got bigger and less redder. Now he's orange... and not a spazz.
I used to have hamsters when I was little. I got my first hamster, Daisy when I was six. She was a Teddy Bear Hamster (If that's what they're actually called.) She was sweet and tolerant of my six-year-old self. One day; she got out of her hamster ball and was never seen again. One of my later hamsters, Ginger, had babies on Christmas morning. ^^ But two died when they were born. (She had three.) I don't have any more hamsters today.
