Hi Koko and everyone,

My red cap Oranda has not been well for a week now. At the beginning he was flipping, lying totally flat and I thought he was dead. I transferred him to a bucket and gave him a salt bath (one teaspoon per one littre of water). Then four days later he stopped lying on his side, then I fed him green pea. But he seems to have trouble swimming upward. When he tried to swim upwards he sinks immediately as if he is too heavy. I have a close look at the bottom of his body, there is some redish patch that looks like a wound, and the scales close to the bottom seems a bit sticking out, I am afraid its dropsy but I have no clue if it is.

Can anyone please advise?

Anne

will be helpful if you can provide a picture

sounds like dropsy possible case.. but hard to verify the wound without seeing it.. the fish might have hurted itself or it may have lost a few scale or scratch or watever.. need a picture..

Hi Anne

Actually it sounds like a virulent internal infection to me, but can you just post your water parameters and the other info requested in the red box, so we can make an accurate diagnosis? Thanks.

Hi there,

Thank you guys for replying. Actually the fish has been in an isolated bucket (salt dip) for a while, I change the water every second day, so the water condition is fine, the ph is 7, ammonia = 0 ( not sure about the nitrate, but guess should be fine consider I change the water frequently). Have been fasting him for a few day and started to feed him pea yesterday. As I mentioned it is jst staying at the bottom, seem like having trouble swmming, plus with the possible wound underneath him.

I will try to take its picture, but seem quite hard to do it though.
