HCA: Hermit Crab Association

In that case I would probably hold off on foraging in that area.

I just fill up a jug of water and rinse them into the toilet. I figure it’s better than the sink.

You’re not going to harm them just moving them out temporarily.

Usually, yes. I would continue to monitor as needed if the scent continues but I’m not sure what more can be done.

I would stick a straw or chopstick into the substrate along the side of the tank. If the vertical tunnel you created fills with water, then your substrate is oversaturated. Dig up your crab and remove any sulfuric-scented substrate. If not, there is no flooding but continue to monitor as needed. Sen...

It may be worth asking. Ant killers can remain effective for anywhere from a few weeks to twelve months before they’re affected by runoff and decomposition.

Have you read our care guides? Those would be a good place to start. Basic care guide: http://hermitcrabassociation.com/phpBB/viewtopic.php?f=120&t=119273 Even under optimal conditions, however, mortality can be high for new crabs. They are captured wild and shipped en masse, which can of course cau...

Do you know what they sprayed? Knowing how long it remains in the soil would be helpful. Rinsing off the leaves would remove most of the surface residue but anything absorbed would be in the tissues.

I’ve been using the one from PetsPioneer, but anything built for enclosures will do.

Springtails and isopods are the top picks for crabitats. Snails are slow moving and would likely be eaten fairly quickly. Rodents are able to attack the crabs and aren’t suited for a tropical setup, anyways. Our plant guide: https://www.hermitcrabassociation.com/phpBB/viewtopic.php?f=39&t=120839 Sen...

It’s not designed for captive animal use, so you’d have to be careful that it doesn’t overheat.

Old news for sure, but an interesting insight into hermit crab socialization.

Mold won’t hurt the crabs but it can trigger human allergies. I’m allergic to mold so I try to minimize it when possible. As for lowering humidity, you could mist less or open up the lid more often. I have a hygrostat that lets me control humidity with greater precision. Sent from my iPhone using Ta...

I don’t know how much of the light spectrum they can see, however Wyze Cams use infrared night vision, which many crabbers have used without reporting affected behavior.

Your crab isn’t carrying food around, is it?

You can always pick up the crab and see if it’s producing the smell itself, but don’t get pinched.
