    what are these aliens?

    Saw these odd creatures attached to my airstone and mostly near the submersible pumps. Tried to crush one and it has a crunchy sound. Very hard also to remove. Are these parasitic or some larvae? How can I remove them? Tinfoil barbs or medications?

    Thanks.

    Don't know but strongly suspect it to likely be some larval stage of a water bug/fly or harmless insect and not a parasite of koi-- although some of the dragonfly larva and other insect larva ( bettles mostly) can prey on very young fry while they are in their early development stages. I would try Dimilin as it is safe but deadly to shedding insect stages, and see if that doesn't get rid of them. JR

    Thanks a lot! Actually these aliens are not mobile and just sticks to a certain surface.

    Will surely Dimilin the pond. Thanks again!
