Koi's and tadpoles?

Question

I put in about 6 tadpoles and all of a sudden some started to disappear.

My Koi's range from size 6" to 12".
Do you think they ate them?

I have a protective cover because some of my Koi's were actually being eaten by an Owl. So it can't be any bird doing it.

Any suggestions?

Answer 1

hi, sure the kois ate them. they eat small things like that, and tadpoles are small. keep them seperated until the tadpoles are bigger.
