Satine was named after Satine the Sparkling Diamond from Moulin Rouge because he's white (yes, I know my betta is a boy, but I loved the name)

Damon was named after Johnny Damon of the Boston Red Sox.

Blink was named that because he hatched premature, being born blind, then was able to 'blink' his eyes open

Gus was named after my aunt's cat that passed away because he looked just like him and the name seemed to fit.
