I chose mine because it was the first time I've seen a female betta and I thought I would give it a try. And I hadn't ever seen a betta with Addie's colors. Well, all the bettas I had as a child and saw my younger relatives with were either red or blue-purple.
...originally I was just planning to get a marimo only... but then I looked at the fish...
Originally, I wanted to get a lady betta who looked exactly like Addie but with white eyes, but she was gone and then I got Addie instead.
For Henry, I was originally tasked with pet-sitting, but then my cousin never took him back and then I was bent on rehabilitating him.
