I have a minibow 5 gal with two female bettas and a male guppy. They were quite happy together. Something happened and Alsace-Lorraine passed away two days ago. I've been watching Orlena (the remaining female) like a hawk for any signs of illness or injury like Alsace-Lorraine's. What worries me is she was usually very active. Actually all three fish were super active and now, she just lays on the bottom. She eats...although not with her former vigor. It worries me as she was always my favorite lil girl. She still comes up to the top and follows my finger but not with the same umph. Could it be she is mourning? I mean missing her deceased playmate? What can I do?
