what are these critters

[grdpder]

Hi -

I bought some xenias attached to a rock and found these two critters attached to it. I was wondering if anyone could tell me what they are. They appear to look like snails without shells. The pic actually shows one on top of another. Are they safe to put into the tank or should I throw them away...

Thanks in advance...

I believe those are stomatellas and good for your tank.

Thanks! Ok, I have attached link to the video I took with my iphone 5. In the video, you can clearly see other crawling critters moving around. I don't know if you or anyone can make out what they are. What are they. They also came along with the xenias I bought. Are they safe? Can anyone help on this?
