Hi . So i had a 30cm arowana 2 oscars and 1 parrot cichild in my 3ft tank. My parrot cichild got cotton wool fungus and my oscars eventually got it as well. So far my white oscar and parrot cichild died while i have moved my black oscar to a hospital tank and treated it with anti fungal medications. But for me the real problem is that my arowana is not eating. Used to be very responsive. Was feeding it mealworms and market prawn and now it wont eat at all. It is also jumping quite often ( like is trying to escape from this tank). Please help. I really love my arowana.
