HCA: Hermit Crab Association

There’s no hard-fast rule but generally it should be tall enough to both hold enough substrate for digging and still have headspace available for climbing.

Thank you! I had seen somewhere that tite bond 3 was safe but wanted to double check. I’m not familiar with Titebond III. I looked it up and it’s made of “advanced proprietary polymer” so it’s hard tell how safe it is. Are you going to use wood glue for the enclosure itself? It’d probably be low ri...

I wouldn’t. The one-month mark is a bit long but not necessarily a sign of disaster.

Cyanoacrylates (superglue) or two-part epoxies are usually recommended for animal enclosures since they’re inert once dried. Other wood glues can be a tad iffy.

No, it’s nice! I always preferred having more in the tank than less to provide cover.

Interesting... this one’s terrestrial. In that case, refer to our care guides for advice. As for getting him friends, that’s up to you. They are found in colonies in the wild but that’s more to do with resource exploitation than social gathering. In captivity many of the longest living crabs are alo...

Chlorine evaporates on its own. Heavy metals and other contaminates will remain but aren’t usually a concern in the substrate.

Oh, I wasn't aware of that! Is there a place I could find it? I'm trying to learn as much as I can about all of this. Also I'm not trying to refute anything or argue in case thats what it looks like lol I'm new to it all and just trying to figure it all out, I hear conflicting stuff and it can get ...

I just saw your post with the links. The admins before me did a massive study and found no difference between transitioned crabs vs. control, which is what we go off of today.

So far no one’s produced any actual data to refute our claims.

The PPS Method hasn’t never been found to be more beneficial than going without. It’s less to do with results and more about what people are comfortable with.

If you know they’re coming from good conditions, though, there’s no need to acclimatize anyways

A vast majority of crabs found on the beach are marine due to terrestrial hermits’ limited ranges. A marine hermit crab is going to be slimmer than their stockier cousins and many have same-sized claws, as opposed to the terrestrials having one big one to block the shell opening.

It takes time for crabs to feel comfortable in new surroundings, so she may just feel more secure there.

If your molter is underground I would leave it. There’s not much you can do and unless you can see it it likely tunneled away from the entrance, anyways. If your molter is not buried and you can see it then I would consider isolation. You don't need an extra tank, a half bottle pressed into the subs...

I’m guessing he only ripped it apart, but if he did eat it it probably isn’t a big deal.

I am going to repeat JJ’s warning to stay on your teacher’s good side. Giving him supplies may not be as welcome as you might think.
