Illness & Symptoms
How long have you had this fish? Over 2 years
How long ago did you first notice these symptoms? 2.5 weeks ago
In a few words, can you explain the symptoms? Started off with bloated stomach and buoyancy problems, was swimming upside down vertically in circles.
Have you started any treatment for the illness? Fasted for 3 days, frozen peas-only diet for 3 days, started to look a lot better so mixed pea and flake food... then got worse again, so fasted for a day and back to peas-only diet... did first epsom salt bath today.
Was your fish physically ill or injured upon purchase? No.
How has its behavior and appearance changed, if at all? Stomach no longer bloated, and she is upright now, right at the top of her hospital tank, but cannot swim downwards. After she is fed food, she loses buoyancy again and tips sideways or upside down... But by the next night, she will be upright again.

Explain your emergency situation in detail. (Please give a clear explanation of what is going on, include details from the beginning of the illness leading up to now)
2.5 weeks ago, I found my Molly swimming upside down, vertically in circles at the bottom of the tank, and bloated. I immediately assumed it was SwI'm Bladder Disorder.

I moved her to a hospital tank and fasted her for 3 days. She was fed frozen peas for 3 days after and she is upright now, right at the top of her hospital tank, and unable to swim downwards. She looked better, so I tried a mix of frozen peas and flake food (just because she seemed to hate peas, and I was just happy she still had an appetite)... The next day she was still right at the top of the tank but was upside down. She recovered back to an upright position that night... But this has become a pattern now after being given any type of food (just pea-only diet now) - she'll tip upside down and then recover to an upright position by the next night. At this point, she has been pooing small droplets - so definitely not constipation.

She has now been fasted for another day and I attempted my first epsom salt bath today (1 tablespoon per gallon for 12mins in the first bath, then 1/4 tablespoon per gallon for 5 mins in the second bath). Nothing in her swimming has changed - she is upright at the top of the tank. But she has had a long, white string poo after the epsom salt bath.

This is the first time I've had a fish sick with swim bladder disorder, so I know my attempt at treating her was probably wrong in many ways. Hopefully, you guys can help me figure out what to do! Maybe another epsom salt bath in a few days? Thank you for any and all suggestions!
