I named my first boy Piras after the main character in a webcomic I really like. The main character is a redhead who is kind of vain and likes to show off, which is exactly what my boy is like 😄 (the comic is called Awaken, and is a sci fi/fantasy comic with cool monsters and really awesome world building, so please check it out if you like comics!)
I named Snoopy after the Peanuts character, mostly because of his spots. But he also kind of gave me a sad look the first week when we we're figuring out what food he would eat that reminds me of the sad eyes my sister's dog gives me when I'm not getting him lol. I started calling Snoopy puppy as a nickname
My girls are Mercury, Jupiter, Neptune, Serenity, Venus, and Artemis. I named the first five based on the Sailor Scouts from Sailor Moon because I originally was going to make my 20 gallon a sorority, and wanted them to have names based on a theme. But after doing more research I decided not to do a sorority, especially since my girls are unrelated and different ages. Plus I don't think Mercury and Serenity would do well in sorority because they're both very feisty, and I know from accidentally allowing Serenity to hop into Jupiter's side of the tank that she is quite agressive.
Artemis' name comes from her color, since she is white with a faint overlay of iridescence all over. I think she's an attempt at an opaque white, since she has a bit of opaque on her head, but her body is close to cellophane. She also has larger pectorals, so she flutters around the 20 gallon looking like the moon. Artemis is the Greek goddess who is associated with the moon and also hunting, so it's a perfect name for a betta 😄
