SIGH... well, after 2 months of fighting off dropsy, my betta is finally starting to give in. he was getting better for a time, but now he has stopped eating, is listless, and seems to be developing fungus on his tail fin.... I did everything I could to help him. kept him warm, kept his tanks water pristine, and gave him epsom salts to help reduce it. i'm not sure weither I should put him down or let nature take its course... i've moved my oto to my 10G in anticipation, since I plan to make my 5G into a nano marine once blue goes to the big rice paddy in the sky....
