Female betta lethargic and refusing meals since yesterday in a tank that tests clean
What they asked
I have a female betta in an established 10-gallon planted aquarium. Since yesterday, she's become lethargic, is resting more than usual, and has refused two meals. She can still swim normally and her breathing appears normal. Temperature is 78°F, pH approximately 8.2, ammonia 0, nitrite 0, and nitrate 10 ppm. Her six rasbora tankmates are behaving normally. Do you have a veterinarian experienced with bettas who can review photos and videos and advise on treatment?
Sorry to hear about your betta. Are you able to set up a hospital tank? Try new treated water with a slime coat product in another container with just her. Observe for signs of any growth on her scales, red pigment, or any balance issues and she will likely need antibiotic or antifungal treatments.

Ask Dylan a questionAnswered from your description alone, without examining your pet. That makes this general information, not a diagnosis, treatment plan, or prescription, and it is not intended to establish a veterinarian-client-patient relationship. There is only so much anyone can tell from a message. For guidance specific to your pet, book an appointment so a vet can examine them properly.
