lol, thanks, everyone for your support!
As it turns out, it's NOT PARASITES!! Whoo! *throws confetti*
not sure why, but I took a really close look at Cinder tonight and the so-thought parasites are literally extra fin growth. I've never seen it before.
And the erratic swimming all over the place? Cinder's chasing his reflection!! :D
So all is well!
I'm not going to change my username, ifish. I want to keep it to honor the memory of my first Betta, Tian-Tian. I still miss him, but Cinder will keep me company for now.
And he's such a cutie! He's fighting with his reflection at the moment, but earlier he was just staring at me in a very peculiar way. I've never seen a Betta fish with so much expression!!
Cinder's such a cutie. <3
