Oh boy...here it goes. Here's the tank. 29 gallon, heavily planted.
There are 9 girls and a baby betta in this tank, along with 3 otos.

Elizabeth.

Etta.

Olivia. I'm pretty sure she's the Alpha, but it's kind of hard to tell.

Rachel, showing off her fin-jury. This is the only real noticeable fin nip I've seen so far.

Ella. This is kind of an old photo, she is brighter now and no stripes. Looks like Rachel's twin, basically.

Nina - probably the most docile. She's hard to take photos of, but is the brightest red you've ever seen.

Rebecca is the small one on the left of the group, I don't have any other photos of her other than this one, but you get the idea.

And last of the bettas, my baby. S/he was living in a breeder box in the sorority when I first got her/him, but escaped during a water change and so I've just been leaving it be. Hopefully it's a girl so I can just leave her/him in there.
