Yeah had a couple emerald crabs early in my tanks life, sadly they did die off.. Hmmm maybe getting another is a plus.. 
Thanks for the info and reminder.

I'm battling a little Hair algae in my SPS despite exporting a lot of Macro Algea and heavy skimming.
The tangs are worthless on this but Crabs especially emerald help a lot. The down Side is they do not live forever. Now every couple of months I add a few more.
As far as skimming Tunze makes a small skimmer that does quite a good job given its size.
