I have five bettas, and will give their names, and explain the meanings.
Sapphire: Female VT (Blue)
She was given this name by my mom, mainly because she’s blue, the color of a sapphire.
Luna: Male HM (Blue)
I had a betta, which was my first, and he was named Luna.
That name just came to me because of the moon, and because someone had a dog named Luna.
Luna, my very first betta, he died two years ago, but I got another one like him, and kept the name.
Santiago: Male CT (Yellow)
He has yellow and blue coloring, which reminding me of a hispanic theme, which is why I chose Santiago.
Nico: Male HMPK (Red & Blue)
Well, this name just sounded really cute for a betta, and was a suggestion from my brothers, so I chose it.
Janet: Female HMPK (Maroon & Blue)
There is a cashier at my grocery store named Janet, the name sounded nice, so I chose it for her.
I have had other bettas, they are deceased or I rehomed them, which are,
Spooler, Luna #1, Fanatic, and April. I rehomed April from my female sorority.
