Are we looking at the shrimp in the lower left? I can't make out anything else in the photo, but I'd agree that all i can see is a skunk cleaner shrimp.
Sorry for the "I spy" quality picture. I can't seem to get any better. Get him out huh? Ruff advise without a tear down. How could I go about that?
That's like telling my 3 year old to stay out of daddy's Nova....not gonna happen! =)
I have pulled many crabs out of my tank with a pair of hemostats. (the tweezers/pliers things Dr.'s use for stitches) I stupidly bought 12 emeralds when I first started my tank as part of a clean up crew. They don't seem to be scared of them. You can reach right into that little hole & grab him just be prepared to stand there for a few minutes. They have a really good grip. I just kinda wiggled them back & forth until they let go.
