Sick goldfish


Recommended Posts

I have had my four goldfish, 3 fancy and one comet for a few years now. In June I got a bigger tank (198L)  as my fish were getting bigger. I also had a bristle nose pleco and snails. Just after I got the new tank I got some more snails ( I now have 4), two borneo sucker fish and 5 harlequin rasboras. (The temperature of the tank is suitable for all). In the last 2-3 weeks my goldfish have started suddenly dying one at a time. One went from being really healthy and was suddenly swimming upside down briefly and then seemed dead. It was taken out of the tank and seemed to come back to life so was put back in. Then it seemed to get fin rot and slowly died. Then a week or so later another previously healthy fish started excreting white stuff and was lethargic. It then died. Now another is lethargic and its dorsal fin is floppy and my other goldfish is lying on its side at the bottom of the tank. I have done my weekly water changes and all parameters seem fine. Does anyone have any idea what could be happening please?
