The water level isn't high enough for them to climb, the heater looks like the only escape point. I doubt they left though, your tank looks like a perfect habitat.

They're mud crabs, so expect them to hide during the day and to come out at night.

Yea, I doubt they left. I would bet they just are hanging out in the moss even at night.

I actually just saw two tonight after the lights were out for awhile. One was in the feeding dish he scurried away when I turned on low light. Then later on I saw two hanging out in the moss.

I was able to catch one out in the open on the side of the tank that faces the wall. Had to squeeze in to try and get pictures. I swear my phone will focus in and it looks great then it continues to focus and it gets fuzzy.

Hm, these guys might not be so cool in invert tanks if they just hide all the time!

I'm sure they're just exploring the moss and will get bored soon enough and explore the open areas once the are comfortable.

Another one was just roaming around in the open so maybe they are just getting comfortable.

Default Molt I Hope

So I checked the tank this morning, and noticed a crab sitting in the moss. So when I turn on the light no movement. As I watch it doesn't move at all. I start to think it died. So I wait some more and nothing. I thought it looks kinda clear ish maybe its a molt. So I moved it to the substrate to get some close up pictures with the micro camera. Do you think its a molt?

I think it is a molt. Take a tweezer to it and try to test its integrity.

looks like a molt to me, the eyes aren't a dark color, if it was a dead crab I think they eyes would be a give away.

Definitely a molt. Crabs don't lose their coloration like shrimp when they die. I bred Mangrove and Vamp crabs and dead ones would retain coloration for weeks until they fully rotted and left their shell behind.

Molts are semi-translucent and crunch when you squeeze them. You can see through the legs, very distinguishable for molts.

So I found another molt. I was able to catch one of the crabs sitting on the outside of the moss. The best picture I could get before he went all the way back in is below.
