I was lucky enough to buy some young GBR's 2 or 3 months ago even more lucky that they were male and female Anyway last week the female went very swollen.I thought she was full of eggs so I was not so concerned but after 3 or 4 days she went back to her normal size and a day after that she went very dark and hid in the plants.She did eat but stopped after day of going dark,she got smaller and smaller until unfortunalty she died yesterday And the Male has started to swell now and I think its Dropsy which is difficult to cure.I very rarely have any deaths in my tank due to disease hence I dont have any meds ATM but I think I will go to my Local Fish shop in the morning to get some just in case.I do around 60% water changes per week and keep my tank in good condition so is this likely to be a one off?
