A few months ago I noticed a small insect looking creature running from some aggitated polyps in the night. Recently I moved one of my leather corals at night and noticed around 10-20 of them scurriing into cracks and holes. They look almost like small 1-2mm insects with two antennas (i think)on their head. They are mostly tiny but I saw one or two that are about 2mm long and they run off as soon as they are discovered. Please any ideas on what these are and why they are hanging around my corals and polyps.
