Jane Doe(my female betta) keeps scavenging around and overfeeding herself. She eats anything she finds in between the gravel. Fasting her in epsom salt helps reduce her swelling and empty her stomach, but when I put her back she just overeats some more. She can't be hungry, because she gets frozen brine shrimp every day(I'm starting to feed freeze dried bloodworms as well). This started two days ago. I'm worried she'll blow up or something. I guess I can clean the bottom and add more gravel, but in the meantime I don't want to stress her out too much. Do I keep her in a separate tank until the gravel is clean?
