so I've seen these little white crab looking things in my tank the past couple nights. they look like a mix of a sand crab and an amphipod and I've never seen them before. I've also already checked the hitchhiker guide from lionfishlair.com and they were not in it. hopefully someone knows what they are and can tell me if they are a problem. the video in the link shows it moving in the very beginning. the first time i watched it I missed it and i had to drag the navigator all the way to the beginning of the video. thanks in advanced for any help
