Potential sick Koi

[DrDave]

Wikipedia has this to say about bloodworms;

The larva of a non-biting midge (Family Chironomidae) containing hemoglobin
The polychaete Glycera, often used for fishing bait
The worm, Lumbriculus variegatus, more commonly called blackworm, but often misnamed by pet store
commonly the favourite food of most betta fish

I wouldn't jump to conclusions and start treating without more proof.:goldfish:

Those are not bloodworms. I feed my fish live and frozen bloodworms all the time and those don't have the right shape.

to asnwer all questions, the pond filter was just cleaned two weeks ago, thats what the picture of the "worms" are from. I have searched the web and it looks like these are blood worms, they look the same as some others have posted.

Very simular to the ones i found in my filter. So Now i have no clue on how or even if i should treat other fish.

looking at those pics it looks very much the same as whats in your filter ..

 

[BBK]

They do look like the same.

Are they fat or skinny? Bloodworms are very very skinny.

They look like blood worms to me. I have them in my filter and my fish LOVE them when i do something in the filter and they come loose.
