Bumps on my Koi

[Muriel]

Does anyone know anything about these bumps on one of my Koi? He's one of the biggest and acts healthy enough. The ice has just been gone about 3 weeks and they all look good except for this one. There are many bumps and the biggest is whitish on the top. No ulcerations. I can't find any disease like this online.

Could it be some kind of infection? What is recommended for a pond 2' deep 24' long and 6' wide in Connecticut?

Thank you so much for your advice Koi lovers.

I'm sure others with more experience will chime in. I wonder if it could be carp pox?

 

[Muriel]

Thank you Tula, I looked that up and it seems quite likely.

Could be koi pox.

Hard to tell from a picture but pox wasn't my first impression. Pox are more like something on the surface, translucent and not as much of a bump, more flat. And the bump is only white toward the top where pox is all white/translucent.

My guess was tumors, just abnormal growth of cells. These fish are inbred so tumors aren't uncommon.

But seeing it person is better than from pictures.

No idea. Actually, I don't have any experience with fish diseases. If mine ever have any issues I'll be lost on what to do.

lymphocystis perhaps.

May I suggest you buy this book The Interpet Manual of koi Helth ISBN 1842860992 (or its revised version) Authors Keith Holmes and Tony Pitham avilable on both Amazon UK and US , you wont regret it and they can be picked up for a song .
What we are seeing as Waterbug has so rightly pointed out isnt koi pox , it may well be a tumour but its more tha likely a cyst of a tiny worm which at this late time of night the name slip's me however I believe one of the girls on line has had problems with these before...
