Our Betta, Moonlight, has darker color on her fins and tail since we got her in March of this year. A similar thing happened to our old Betta who was pale grey at first but developed a sparkly blue color over time. She also had a black dot on her body that disappeared in a few months. It looked fatal at first but it wasn’t.

Thanks! She’s more confident now but she’s nipping at the catfish’s tail.
