Normally we’d request pictures of the big claw but that looks like a PP to me

That behavior is normal for new crabs. They will become active when they are comfortable, which may take a while. Having cover and hiding places so they aren’t in the open will help Cooking foods is optional, and their hard claws can handle a variety of textures. Not appearing to eat large amounts o...

Honey will be okay while Hazel is gone, if you bought a new crab every time only one was up you’d have an entire colony. Some crabs even do okay alone permanently To answer your question though, a 20 can support three smalls okay but will require an upgrade after a few years Sent from my iPhone usin...

Not experienced with this species but my two cents Veggies and fruits with protein options should suffice, if you want to you can try a commercial fish food as well (they do make some for shrimp or crabs, though quality will vary). If you wanna offer a cuttlebone for calcium that’ll work too. You ca...

It should be fine. They may be spooked initially but I’m guessing they’ll eventually get used to the noise and vibrations

In captivity PPs tend to prefer most lightweight turbos and have a habit of refusing other shells. They also need a round opening that they can fit through and the correct spiral shape

There are many reports of crabs going back and using the wheels repeatedly (including mine), suggesting they purposely go in for enrichment. Sometimes they may need to be enticed into entering the wheel for the first time but after that it will likely become a regular occurrence Sent from my iPhone ...

Is the water kept warm enough? Is there any water movement or aeration? I am not an expert in megalopa rearing so I will direct you to some resources.

It does sound like you have a mold or other fungus growing in there. Anything that big I personally would remove, but I’m willing to bet it’ll come back eventually

It could be an old piece of exo that got pushed to the surface by digging. For now I would leave them be, I don’t think there are any benefits to digging here

He is adjusting to his new space and feels most secure in the corner

When he’s ready to leave he will dig his way out. By the time his exoskeleton is fully hardened he will be more than capable of making a new exit

The tunnel shouldn’t be too much of an issue. Time will tell but if you only collapsed part of the entrance I’m betting the crab is fine Sometimes crabs just choose a spot and sit there. If he likes it leave him be, although more hiding places may make him more secure. He’ll walk around when he want...

Agreed, this is normal for new crabs

They would, yes. Stocking is weird and simple “x gallons per crab” rules oversimplify, although I’ll admit our stocking recommendations are a bit complex.
