would it also help to put her in an "in-tank" quarantine holder to ensure she's getting food and not rubbing up against the ornamental structures or would that just stress her out even more?

My molly's condition is getting worse as time goes by. Her tail fin is deteriorating further and now instead of horizontal to the bottom of the tank she is vertical. She hides and tries to get under or close to the tank structures throughout the day. She moves a bit when it's feeding time as she's trying to get food. Honestly, she looks dead with the exception of her pectoral fins moving (sometimes fast, sometimes slow). I've used Bacterial Removal solution, Aquarium salt and Epsom salt bath. I've run out of ideas. Whatever it is clearly isn't contagious as the other three fish seem to be fine and this has been going on for well over a month. Any ideas...???

She has never tipped over to her side. It can still be swim bladder if she remains upright? thank you

this is my first tank. what do you mean when you say "water parameters" Does this test strip answer your questions? thanks for the help

I have a 20 galloon tank with 1 Panda Angel, 1 Golden Wonder Killifish, 1 Black Molly and 1 Gold Dust Molly with a balloon belly. I've had this tank since June 2020. Tank is cleaned weekly to bi-weekly. Never more than 25/30% water changes. Each time I add a biological buster to account for the percent of water removed. My Gold Dust Molly has been showing signs of illness over the past four weeks. She will not leave the bottom of the tank and typically remains in the same spot all day long. Her back fin appears to be immobile. Her crescent shaped tail fin has collapsed down and there does seem to be some (minimal) sloughing of the tail fin as well She will try her best to eat any of the flake food that falls to the bottom but can't navigate herself well and typically only get he food that floats right in front of her mouth. Within the last week I have added a bacterial infection resolve solution and finally added 4T of marine salt to the tank. Her symptoms have not gotten any better. Looking to see what my next step should be. Thank you
