Glass Anemones?

[Siejuban]

When I turn off the light, one thing that is transparent white with solid white strip on its tentacles, look like glass anemones, so far I can see only one of it. Is this Glass Anemones? I wonder, since it will hide when the light turn on. At a later time, after the tank is cycled, I may purchass peppermint shimp to get rid of them (if there is any). But I heard Peppermint shrimp will be confused by other kind of shrimp, like camel shrimp, anyone here know how to ID those shrimp, so I won't buy the wrong one. So far, after I did some research on those shrimp, I can't only know a little about it.
