I'm so stupid. I feel like an ass. I've had my 55 gallon planted tank up for almost a year and all my fish are still alive. For the moment anyway. Last week I did some rearranging of my plants because I plan on getting some more. So to make room for the new plants I moved stuff around. It stired up allot of gunk from the gravel too. After I was done I let the filter clear the water up for a couple hours and then I did a water change. Well I forgot one important step. You quessed it I didn't get to cleaning my canister filter. Well now all my fish have bad bacteria infections. The Gouramis have Dropsy and the Neons have something else, but it's not good. I feel awful. I started treating the whole 55 gallon with Maracyn-Two. This is the last day of treatment and I think I will repeat it for another 5 days. Very sick fish. Has anyone actually ever cured Dropsy or should I just put these poor fish out of their missery. They look like they are ready to pop. Somebody shoot me I deserve it.
