Red cap Oranda with dropsy


Recommended Posts

  • Regular Member

Hi all, I am seeking advice on my Oranda. I have an odd situation. Basically about 4 weeks ago my cute red cap Oranda died of dropsy [emoji3525] now I have 4 other goldfish in the tank and they are all fine. So 2 weeks ago I bought a new red cap Oranda to add to the family. Now out of nowhere he suddenly has dropsy as well and all the other goldfish are fine. Lucky for me I seemed to have got to treatment before the pine coneing stage, as I am now aware of the symptoms because of the passing of my other one. The swelling in the stomach area seems to be going down. However what I want to know is what should I do with my main tank, the Oranda is currently in a hospital tank but what are the chances this one got dropsy as well?do you think I had bad luck with the purchase and inherited the issue from the aquarium shop? or is their specifically a bacteria that effects only the Oranda breed? In which case should I be treating my entire tank with all the other goldfish ?


Few deets, I run a cannister filter and sponge filter, tank is 182 ltrs, the fish are all only around 1.5 to 3 inches long and I do water changes 25 percent once a week and water condition with prime. I have 0 nitrate,nitrite and ammonia. Oh levels are 7.6.


Any help is much appreciated.

Yes, we definitely need more information. Dropsy is a symptom, more than it’s own ailment, and understanding the tank conditions, tap water composition, age and medical history of each fish helps us get to the right treatment more quickly. This is also why we recommend a non-negotiable 4-6 weeks quarantine of any new livestock or plants, because not a one of us hasn’t been burned by sticking in a new someone and having the whole tank get sick. Sometimes catastrophically.
