Hi all! New to the forum. I have a betta named Lulu who just doesn't seem right. She's actually my daughter's fish, but she was brought home to me during the summer while my daughter is out of college. At first she seemed fine, happy, energetic. If you would go up to the tank she would swim up to look at you and seem very interested in anyone who gave her attention. When I would go to feed her she seemed to almost wag her tail she got so excited. Now, she is lethargic, she stays on the rocks near the bottom of the tank and doesn't swim much. She's also lost interest in any of us at home. My daughter and her boyfriend went to a local pet store that specializes in fish, and they told us not to feed her so much (we were feeding her six pellets of Tetra Betta twice a day), and to just give her two pellets a day. They also told us not to clean out the whole tank, just about a third of it and replace it with the PH balanced water they sell, because the bacteria that puts oxygen in the water was removed when we totally cleaned out the tank. She seems somewhat better, but she's still so lethargic and she seems depressed. Can anyone help me? Jonathan, my daughter's boyfriend thought her eyes looked a little bulgy, but I don't see it.
