The Shrimps Are Back In Town

After being very elusive for a few days the Ghost Shrimps suddenly both made an appearance a few minutes ago.

For a couple of days I've only ever had a glance of one of them, hiding in or on the cave. To be honest, I've seen so little that I did think one had died and at times they have hidden for so long, I assumed both were gone.

But then suddenly both Ghost Shrimps made an appearance on more obvious rocks and there's one (or is it both taking turns) scurrying around the water like they were when they first went in a week ago? Maybe they have both simultaneously molted or something, but their behaviours have changed in the last 10 minutes.
