Question
There has been worm like things coming out of our pregnant koi fish and we want to know if she has worms or if it is just something to do with her eggs?  If it is worms what should we do with her and will the other fish be affected?
Thanks for helping,
Carlee

Answer
Hello Carlee!
Worms should never be coming out of your fish. There is a serious problem here.
Try to determine what the parasites are and then isolate and treat the fish as quickly as you can.
Take a close look at these parasites and then use the search engines "images" function to search for fish parasites to determine what exactly they are so you can find an appropriate treatment.
