One of my crabs, Spunky, dug down, presumably to molt, on 7/22. He showed back up on 8/11 and I assumed he was done molting. So then he changed shells multiple times into bigger and bigger shells for a few days and on 8/30 he disappeared again until today. Either Spunky, or someone else, is back in the shell that Spunky was in when he dug down on 8/30. He looks a lot bigger than he was just a week ago. When he dug down (and even after he was back on 8/11) I would consider him a small. Now he's definately a solid medium. Can they change that much in size during a molt?
Everyone in my original tat is under ground so I'm trying to figure out if it's someone else. Hopefully not, because that wouldn't be a good thing for Spunky since it's the shell he was in. There are two bigger crabs in the tat. One is a medium and dug down 8/1. It was in a different area than where this one came up and there is a window to where he is and I think that one is still there. The other one was just slightly bigger than Spunky was originally and was very much lighter in color.
I've only had hermies for 2 and a half months and only one molt completed (unless this is another crab) so I'm not sure what is going on. Any ideas are appreciated.
I've noticed that when the crab first comes up they just sort of look the same and your bummed because you're expecting a bigger brighter crab. But after a week or so the exo seems to really set and the color gets brighter and they finally seem larger. Mine always take a new shell within a week. Sometimes it can be hard to tell if they really molted or if they just destressed, especially with new guys. But look at the feet for heels and the eyes for lashes. When you see the toe nails you know it. They are very long. Some crabs have a small black nub but a fresh molter will have heels that can be quite uncomfortable to hold because they are sharp. My lastest molt has a very purple/pink color and after her molt she is neon. And one of my little guys is very white and after his last molt he has much more purple. And when they put on a bigger shell it also makes them look bigger. I wish I still had Amelia's original shell, I'd snap a pic of it compared to her now. The shell was damaged so I tossed it but it was only I'd say slightly over an inch in width. Now she's had 2 molts and is in a shell (which is a bit larger on her but not to much) and it probably measures a good 2 inches across.
And they usually come up in the same spot or come up at a sort of angle so if you know that is where he went down then that's probably him

Yeah, Sara's right-those were the first questions I was gonna ask. Do you remember if he had (or does now) little black pokey things at the ends of his feet, or looked more hairy? Those are signs of a fresh molt.
If he looks significantly bigger may mean he's someone else. When my small guys molt they actually look smaller (and even a little paler) when they come up. Apparently, with hermies, they are always in a molt stage. The time between molts is actually both a post molt (after the last one, while they are growing the new exo) and then a pre-molt (preparing for the next one) stage. They do get bigger of course; that's the whole point. But when they finish and come up, they are still working on growing and hardening their new exo, so they can look smaller. I have heard that taking a bigger shell is common (to give them growing room), only a couple of my guys have done that. I wouldn't worry too much if it seems someone else is wearing his shell-THEY DO A LOT WHEN WE AREN'T WATCHING! ;D When my little ones came up from their molts, the beginning of August, I found a crab in my Toki's shell that I knew couldn't be Toki (he has a huge and bulbous BP in relation to his body size). So then I started wondering where Toki was, if someone else was wearing his shell. Then I saw two other guys Toki's size in 2 different shells. Only by looking at pictures I had taken was I able to realize that Toki was one of those other 2 guys! That shell he was in? Nowhere to be found even now,hh. I also realized that Toki's BP doesn't look so big in proportion right now, because he hasn't fully hardened from the molt and finished his growing. It REALLY helps to have pictures....otherwise, you might never know,hh!

I second the pics! I've learned to take a bunch of pics noteing color and a good BP shot and this helps to tell the difference. I use my photobucket to keep this all organized. Here you can name label and date it all plus it's easy to share! After a while you get to know who is who but when you first get a bunch it can be confusing to figure them all out.
Do the markings on top of their head/body change when they molt? Could that be a way to keep track of who is who??
c. variabilis x4: Ginger, Mango, Fudge and Caramel Ginger has been with me since November 2011. Mango, since August 2013 Fudge and Caramel were adopted in about November 2015 from a local crabber along with Ziggy who was the mother of my first lot of babies but died about a week later. + about a 13 baby crabs as at 26 Dec 2016 (DOH 4th December)
Yes I had a medium pp that I always new because after 2 molts he still had a tan spot on top of his head behind his eyes....but now that he's a large and had lots of good foods....you can't tell by that mark as he is now all purple.
Like everyone else said - more often than not they come up looking a little smaller and you likely won't notice any growth right off the bat.
However, I have had crabs go down for a molt and stay down so long that when they come up they're past that "smaller" stage and seemed to have doubled in size. Rarely have I seen that happen - but it does happen. It might be that they stay hidden and I just don't notice them through a couple of back to back molts or it might be that they truly can grow that much in one molt. It's hard to say, since in these instances (like I said) I never see them between the time they first disappear and the time they come back all huge.

Most of mine seem to change into smaller shells before going down to molt and then stay in them for a bit until they strengthen up a bit. Then they change into bigger shells. I do have a few that never seem to changes shells at all even before and after molting. It is interesting to see them harden up, and change in colour after awhile after a molt.
