I’ve had my betta for around 6 months now, I got her from an amazing local shop focused on fish specifically. I have her in a 10 gallon tank, cycled, heated, decorated and filtering. She’s been doing amazing until Monday, that’s when I noticed that she was just sitting in the top right corner of her tank. The only time she moves is to eat (sometimes) but then she goes right back to the corner. She seems kind of bloated and has something white on the bottom of her belly. I’ve tried researching what it could be and what I can do but haven’t found much. I’ve already tried a 20% water change, the pea trick, vacuuming the gravel, and I’ve tested the water (not all on the same day of course). All the numbers I’m getting from my tests are great so I’m at a loss! Please help!
