One of my coworkers said today "I should get some girls like you so I can have more than one betta!". I love her, but I tried to make it sound as complicated as possible to dissuade her. I think I got her to change her mind when I told her I'm putting fancy guppies in my paludarium and they look just like tiny betta that can be housed together. To be fair, she's gone a long way since she started keeping her one male betta, Ruby. She started with one of those tiny "self cleaning" tanks and I finally got her to upgrade to a 5g about six months ago. I can't get her to put a filter in it though... but she is diligent about water changes. He seems happy and healthy when I see him. Little steps with her, I guess. Little steps are at least better than standing still.
