I have a female Dwarf Gourami. She looks gravid or swollen and will not eat. She just hangs around the top of the tank. hat could be wrong I put a few drops of Methylene blue in because that seems to be a cure all. That has not worked I put food in front of her face and she won't eat. Do you think I should clean the tank again and add Parasite guard. I just cleand the tank yesterday but I don't think I should mix the medications. Thanks for your help.
