Frida is on day 6. She's always been a "fat" fish, but this is beyond that. I removed her from the community/betta sorority tank after finding her lodged in a plant. After putting her in a pint container, I observed her belly to be so distended she only dragged it along the bottom, and would list sideways. I fasted her three days, epsom baths 2x/day, shelled pea which she wouldn't touch. No poop. Her belly has gone down enough that she's no longer listing, but it's still weighing her down. Curious if she even had an appetite, I tried a small bug bite flake yesterday. Nope. Last night, she readily ate a thawed bloodworm. The parameters from her usual tank: tannic, 0/0/40. Neutral pH. No other fish affected. I noticed two small red spots on the side of her belly. No pineconing. What now?
