I just went to play with Suchin, one of my two
female Bettas, when I noticed something was protruding from her mouth. It looks like, well, strangely enough...a really thin fishing line! It's sticking out of her mouth about a centimeter or two.
I have NO idea what it is, and I can't really examine it because she's my quick one. She's very active and when she sees me, she's even more active. But it oddly looks like a very thin or fine fishing line.
And if it is? I have no idea how it got in her home! Nor why it'd be sticking out of her mouth.

I mean, did someone go fishing in my Betta's tank?
I'm open to thoughts and suggestions. Should I attempt to pull it out, assuming I can even grab ahold of it? What should I do?
