We're dealing with our first surface molt currently. One of the crabs that we adopted last week was probably just about ready to molt, and in the hassle of moving he was too weak and decided it was time for an above ground molt. Fortunately he found a very large shell in the tank and climbed inside, protecting himself between the two shells from the other crabs. This also made it easy to lift him out and place him back in the ISO and give him some overhead cover. He was in the just barely moving, not holding onto the shell stage at the time. The following morning (today) he looked just about the same but was moving a little more, clearly getting ready to shed. By the end of the day today the exo is off, and the soft pinky is happily munching away at it. I've never seen a molt before since they've all molted underground and away from the glass, so this is a pretty cool experience and fortunately it looks like the crab will be okay! How long should I keep the crab in isolation - just until it is moving around a lot again?
