I found a 14 gallon tank on sale with a heater and filter, and couldn't resist setting up a sorority. I've got 5 little females in the tank now, 3 CT and 2 VT. The smallest one turned out to be alpha.
There was a little chasing and body bumping at first, but today they have been fine, and nobody's fins have been nipped. It was largely shows of bravado. The tank is filled with hiding places and plants so they can't chase each other far.
I'm so excited! Aloine, Nymeria, Felurian, Arya, and Danaerys all seem quite happy.
Thank you for all of the information on how to set up my tank successfully!
