I had to remove my female betta from my community tank. She was always harrassing the other fish, mostly the platys and algae eater. I found a cute gallon size plastic brandy glass at walmart, put in gravel a few plastic plants, and she seems to love it in there all by herself. She spreads her fins more now that she's got the whole bowl to herself. I also took one of those book reading lights and clipped it to the rI'm of the bowl. I turn it on at night is it's soo cute.
