Well i picked up this guy 2 days ago and he seems to be doing ok. (i've heard that the first couple days are the most crucial for these guys because they have trouble transporting and acclimating) He didn't move much till today, just stayed on one rock but traveled from the back to the front to get out of the light during the day. Now in about the past 2 hours he's gone from the rock that he was on in the picture all the way to the top of the glass in the back of the tank. I know melosu has a couple of these guys so i figured this would be the best place to ask this question. He is all the way at the top of the glass at the water line, and i know they can't be exposed to air. Will it sence that it is at the surface and stop moving or will it expose itself to the air and die. Right now it is positioned in a way so that the arms that are at the surface are stretched flat to be along the water line and submerged, but it looks like there is a small portion of the arms that are slightly breaking the surface of the water. Is it normal for them to do this much exploring or stay that close to the surface. Here's a pic of the new guy from earlier today. Thanx in advance for any tips or advice.
