Betta Fish: Josephine is a little bitch

I thought the females were nicer but Josie is a MEANNN lady. All of my males have been sweeter than her so far. I put a few guppies in her tank to remove the biofilm from a new piece of wood and she turned murderous on them. (I removed the little guys right away, don't worry)

My finger in her tank- absolutely not, bite bite bite. My finger above the water, absolutely not, more biting. My finger on the othet side of the glass, absolutely NOT- BITE.

Not to mention how GREEDY she is, holy COW. She will eat anything and everything.

My little Josie is stunning though, so it's okay.
