My dad's baby arowana was suffering from fin rot and ich for almost 3 weeks. I was the one who's always water changing, giving meds, feeding his aro since it got sick and I did everything I could to save it. The aro got worse, almost all of it's fins and scales are gone and you can see the muscle at the tip of it's tail. I suggested to him few days to put it down to end it's suffering since it won't last for very long then he told me that "it's still alive and i'll wait till it die". I feel so bad about the fish that I decided to put it down when he was doing something at the backyard right at this very moment. So did I do the right thing?
or I'm just a crazy bastard?
