Something in the rock looks like a centipede. I just noticed it today as I was watching a new addition to my tank. I tried a bright flashlight to get a better view and it retreated back into it's hole. Could be nocturnal ? Any ideas ? Thanks.
That was lucky on my behalf, i found one of these late last night/early morning. It was sitting in some new soft polyp i brought last week, I was gonna get it out.
