My titanium has been floating for about 2 weeks now. HE still eats fine so I fed him nothing but green peas for a few days and then I fed him nothing for a few more then I added epsom salt then dosed the tank with metro then added a little meth blue. still floating still able to eat but I think his stomach is starting to become distended. I did all this with 25% wc's every three days. SHall I watch him slowly die or can I do something better?
