possible hitch hiker?

[Zerandise]

under a patch of red aglea today i see a large pod bigging a tunnel. i watched him go down the tunnle and drag sand back up with him. i noticed just under the algea about 30 little white shrimp looking things. they look like a cross between a pod and a shrimp however they are in the colom not on the sand/glass. they are very small and bone white. I cant tell if they have legs or not but the do have a tail. cant see iwhat kind of tail yet but it is there.

unless i get a macro lens for my camera soon i wont be able to take a pic of them.

I know an ID is not possible without it.
