Hello! 2 days ago, our female betta “Pearly Opal” quit eating, started hanging out in the top corner of the tank, with huge gasping breaths for air. We recently cleaned the 2.5 gallon Fluval Chi tank and I had the water parameters tested. I was told they were “perfect.” Over the course of two days, she became very bloated. Yesterday, she started pineconing, and today she has white cottony growths, swims sideways and is in obvious distress…she keeps going from the top to the bottom of the tank. Help! Is there anything I can do???
