snails/worms? living on my astrea snails?

[fmelindy]

yeah, I had the exact same thing in rather large numbers living on the shells of my turbo snails. Didn't seem to harm them at all and I observed them picking at the rocks as you did. They also seemed to move over the shell and even kept the shells clean. Too bad I didn't get pics of them. I just assumed they were like some kind of "hitch-hiker snails" but I'm curious as well..

I have recently discovered the same thing happening with my turbo snails, one snail has 6-7 critters living on it.

Did you ever learn anymore about these hitchhikers? Do you still have them or did they eventually separate?

[Melina]

No, I have not been able to learn more about these critters. I still have them. They are still on the shells... have not separated.

Strange, I can't find any information either. They look like babies to me, the shells are forming identical to the host snail. I'm betting they detach one day.
