HCA: Hermit Crab Association

Hello! My crab has been changing shells a ton lately and I don’t know why. I have seen him change into 4 different shells. Every time, he is in it for an hour, then just switches back. I have all my shells on my 2nd level and my crab would throw the shells back onto the main level. I don’t know if m...

Hello! I am about to install a heater and I just realized, where should I put my crabs while it happens. I do not know how much the heater will raise the temp, so I want to adjust the thermostat so it works well and I can leave it alone. I think I might take my crabs out of the tank just in case som...

It might have been because of the temp. I read Hermit crabs can lose legs due to stress because of low temperature. Your crabs could have been fighting too. Is another crab wearing the shell of the dead one? All of my crabs are the same size so they don’t fight. They established a hierarchy and leav...

This is a great list for shells that PPs like. https://hermitcrabassociation.com/phpBB ... hp?t=48249
Maybe try soaking shells in saltwater. Try murex and pica shells. My crabs were in those when I first got them. Maybe tape the lid shut to prevent escaping.

I am about to order a heater from the bean farm (the 10 gal heater is finally back in stock) and I have a few questions about the setup. I currently have the tank on a wooden dresser. Would that catch fire with a heater on the back of the tank? I also have a big piece of Mopani wood in the back of t...

Hello, I recently remembered that I have some leftover fake aquarium plants from a previous fish tank. I was about to add them when I realized there was some glue between the bottom of the plant and the plastic base. I looked it up and it said it was called hot melt glue and is commonly used in fake...

Ok! I was just worried that his shell might break. They are in pretty thick shells. Thank you!

Right now, there are 6 shells in the tank. It is lucky that my non aggressive crab tries to stay out of the aggressive one’s way. He doesn’t want to start a fight. He just avoids him.

I have surprisingly never had mold in my tank. I heard lots of crabbers have mold trouble. I guess I’m just lucky. Thanks!

Okay. Thank you! I’ll look for it the next time I go to the pet store!

I checked out the shell guide the last time I bought shells. One of my PPs is in a Mexican Turbo and the other is in a Petholatus Turbo. When I first got them, one was in an Apple Murex, so I try to provide one of those. The other one was in a pica shell when I got him. I want to buy a bigger size o...

Hello! I have recently installed a 2nd level to my tank. I realized that with more height, the closer my PPs are to the mesh lid. I have had a crab trying to climb upside down before in a smaller tank and I took out his way up there soon after. I recently remodeled the tank and now, a different crab...

I do have an extra dish. I can try that. Thank you!

Looks good! They will love to climb it!

I boiled my cholla wood for 5-10mins and it is doing good.
