Pleasant find

[Dearth]

So after coming home from work this morning I took a quick flashlight look in my tank and I discovered I have 2 crabs that I am assuming are hitch hikers both appear to be porcelain crabs. I never saw them until this morning and am assuming I got them from my last J&L order 2 months ago when I got mushroom covered rocks. Must say it was a pleasant discovery.

Hoping that I can seem them again and snap some pictures both had nice markings on the shell.

What's your most unsuspecting hitch hiker find?
