I have a very bloated angelfish that is acting, looking, and eating normally otherwise. There is no sign of pine coning. I moved him to a 10 gallon QT waited a day and fed a crushed up sweet pea. He spit out the first bite and refused to eat any more. I fed him some live baby brine shrimp which he gobbled up so I did that for a couple days and observed for any signs of poop. There was and still is none. After 3 days in QT doing this, he was still bloated yesterday evening. I decided to dose the aquarium with 2 tbsp Epsom salt and start him on metronidazole food yesterday evening. I fed medicated food again this morning. There is still no change today. At what point do I need to do a water change to remove the Epsom salt? I could find plenty in dosing, but not how long to leave in tank. Any other suggestions on how I can help this guy get cleaned out? Thanks for your help!
