My cheating acro crab!

[LowCel]

I was just now looking in the tank with a flashlight and I couldn't believe what I saw. My acro crab was out cheating on it's host birdsnest coral. What is this world coming to? Even crabs are cheating now?

Anyway, is it common for a crab to just decide to move one day? What's weird is that the birdsnest is a colony but the green pocipora he moved to is just a frag. Is it possible that the birdsnest is just getting too crowded for him?

Here is a picture of him "cheating in action". Sorry about the quality, best I could do with just a flash and no light to focus. He is just hanging onto a green pocipora frag.


Here he was before, when he could still show himself in public....before he was tempted by that "sl*t" pocipora.
