Aphids on snails
 

I have little white things that look like aphids on my snail. I can't rememeber what type of snail it is, I've tried to look it up and have come up with nothing. There were originally 3 of them (this type of snail) and the other 2 have died mysteriously. I was wondering if the aphids are the culprit. They are about a milimeter in length, white, rod shaped, have antenna.

I was also thinking they may be possibly babies, but am not sure. Does anyono know where I could find the average reproductive cycle of a snail.

Any information would be helpful.

Thanks

Could be pyramid snails - I had then infesting the astreas in two tanks for a bit, but they seem to have died out.

No def not those, they have no shells as far as i can tell

Copepods

O really are they hurting the snail at all then?
