Betta Fish: Thetis’s Glow Up

I've had this girl since my birthday last year, December 27th, and my god she has had SUCH a glow up! I knew the conditions a betta was kept is showed in their appearance, but I didn't expect her to change this much!

Please don't mind that she's in a cup in the most recent photos, if I don't catch her like that she will gorge herself on the food for the cherry barbs
