Question
From what I understand, I have blood worms in my pond.  I have Koi & Shubunkins in my pond as well- Are blood worms harmful to my fish???

Answer
hi There!

If your fish are doing well, you shouldn't worry about the bloodworms. They are actually sold commercially as fish food.
They could carry some parasites that are harmful to fish, but if your fish are healthy, leave them alone.

Good Luck!
