Hey all just got 2 Emerold crabs 3 days ago, they were hiding when I first put them in. Now, they rund around the sand bed lookign for stuff to eat, that's when I noticed little things running around the crab's bodies. any one know what it is? Is it some kind of parasite? The thingies looks clear about .1 mm in size, real small and they run real fast. I plan on getting some small fish soon...
Should I be concern?
