My female beta is almost 2-1/2 years old. A few months ago, we moved her from a 1-1/2 gallon cube to a 10 gallon tank with filter and heater. She had always done fine in the 1-1/2 cube and I completely changed out the water every few weeks (now I've read this was incorrect but she was never ill once.) After about a month in the new 10 gallon, she got pop-eye. I went to the pet store and they recommended Microbe-lift artemiss (they have no other antibiotics there except beta-fix) and turning off the filter so she could rest. I did the artemiss for at least 10 days. She had been on death's door just lying listlessly, not eating. She revived and was super happy for a few weeks. On Christmas Day, she stopped eating. She hasn't eaten since last Monday now. Her lips are swollen and she has a tiny bit of white fluff above them. Other symptoms are staying at the top of the tank, swimming in little circles, and if she goes near the filter while it's on, just getting pushed around by it. I have done so much reading and seeing so much conflicting info, I didn't know if I should try to the Artemiss again. I did. I did a partial water change about a week ago. Should I do another one? Leave the filter on or off? (because it seems hard for her to rest with the current pulling her to and fro), Should I use the artemiss for more days? (I also took the actual filter out because the pet store person told it'd absorb the medicine) The fish doesn't seem particularly miserable like it did with Popeye but it's almost a week since she ate and she shows zero interest. I'm very confused after doing so much reading, how much I should be cleaning the tank. I thought weekly changes, using the siphon about 50% was ok. I hardly see any poop come up though. Should I stir up the rocks first? Any advice you can give would be great. It's been seven days almost of watching her constantly, and waking up daily expecting to find her dead. This fish is such a fighter, so smart, and is so important in my family. Thank you.
