Betta Fish: RIP to my pretty lady Petals :(

She passed suddenly sometime yesterday early morning. I turned their lights on to see the shrimps having a big feast. She was very healthy and active, no issues leading up to her sudden passing. I only had her around 6 months, and nobody else is sick or having passed so I'm assuming she was a lot older than I thought :/

If anyone has any idea what could have happened to her id appreciate some insight, but otherwise SIP to my pretty Petals 💔
