Quiz -What is shown in the picture

[anglfish]

ahh you guys.

you a right my camera sucks. instead of spending all my money and more on the tank I should seriously upgrade my camera...

it has a macro mode and I know how to use is (thanks for asking though), but the problem is that at night with just the moon led light on I can't see on what I zoom in. have tried it a few times and found that some surrounding rocks are real clear but not the crab that I actually wanted to have on the picture. so I'm pretty blind and just shoot 100 pictures hoping that I can zoom in on the file but .... well.. that doesn't work as we can all see, (or not see for the people that don't even see the attachment)

I guess I will have to wait and see what happens. Even if it is a Xanthid (or whatever they are called) non of the articles I read really went into details "how" destructive they are. He seems pretty cute and was just eating some algae off the rock. could there really be a waiting to be released?

does the form of the pincher give away whether the crab is predatory or not?

how would one even catch a crab without taken all rocks out?
