I didn't know they had nems interesting little critters, I have only seen them acouple of times and not for very long once years ago and I helped Leah get hers back in her tank as it came out on her rocks. quite fragel critters. once the crab was in the water it went straight in to the rocks again so I did not get to see it very well. I'll have to look them up on the net.

I had a seabea nem in my DT and it kept moving to areas the the fish swim more often and when he moves there the fish just go else where. I do believe he is trying to catch dinner. I have since moved him to my kids 25g he has now settled down to one spot unless he is disturbed. He has bleached out a bit in thier tank. I will watch him closely and se what happens.
