my betta has dropsy. hes been ill for about a week now maybe longer. ive tried evrything to try and an help him but nothing has had any effect. his belly is very swollen and his poop has been white and stringy. i tried feeding him peas and have been treating him for internal parasite but nothing has worked. hes in a sorry looking state today and looks so uncomfortable. do i let him pass away or put him to sleep. i couldnt stand it if he was in pain. out of all the fish i keep hes my all time favourite. so much personality. im really gutted.
