Anonymous said: I've recently upgraded from a 20 gallon to a 75 gallon and ever since, my four hermit crabs just seem kind of lifeless. my jumbo (who is usually climbing all over things) has been hiding out under the huge log in there and my smaller three are always in the same spot. I'm kind of worried as they almost seem depressed. Two actually just came up from a molt like three weeks ago, so it's not that.
It could just be adjusting to new surroundings. Especially if there’s new substrate involved, crabs can get a little finicky about things.
Make sure your temperature and humidity aren’t having issues as well.
Anonymous said: Until I can get an under tank heater (to use on the side above the level of substrate, I believe is best?) is it okay to just use a regular heating pad that people use and put it against the side of the tank? It's just one of those ones with a low med and high setting that people use for aching necks and stuff. Is that okay for now?
As a temporary heater it should be fine!

I hear theres a thing that you can stick on the wall, and that would be the best option for me (since I dont have the funds or space for a lamp). Can you tell me the things I should avoid and look for in a heating, pad, thingy? (Also what they're called if you couldnt tell I have no clue lol)
Heating pads on the side are the best. They’re just called heating pads! Sometimes they’re labelled as “under-tank” but they don’t need to be.
sharped0 said: theres a bunch of what i assume to be aquarium sealant in my tank at the seams/corners (it's blue and peels like hot glue if that helps id it). Is this dangerous for my crab? I know I shouldnt put anything in there he cant eat, because they like to nibble on everything. I know small ones can use it to climb.
It’s completely safe.
Anonymous said: Three of my crabs are starting to huddle together in the corner of the tank a lot. It was just two purple pinchers at first and now my Ruggie is joining in. Could this be a sign that something in the tank isn't right? I see them there more often than not, but I hear a lot of climbing at night, so I'm not sure if they're being lethargic. Sometimes they look limp, but they respond well to noise. Should I worry?
Crabs do this a lot! They’re pack animals, so they kind of huddle. It could be that they’re a little chilly though.

I personally don’t put anything painted in my tank, but things that have a glossy paint should be fine.
Anonymous said: I'm going to get a bigger hide for them soon, there's no way for hi to fit inside the current one. He's twice the size of the opening. And I can't get any more sand for about a week, unfortunately. I don't get paid until then. So I need to know what to do until then. How to make it big crab-friendly. While also accommodating the little crabs. This is all in a ten gallon tank, too. So I'm trying to still keep the salt water, food, and fresh water and hide in there. D:
You should be fine until you can pick up more sand! Everything should be fine, actually, for a little while. If you have something you can use as a makeshift hide until then it should be fine, but I would try situating the hide near a corner, and outside of the tank, covering said corner with a cloth or something to block the light out. It kind of creates an artificial safe zone.
Anonymous said: So I just spur of the moment bought a bigger hermit crab. The only two I have are really little. Like it takes me a few minutes to find them in the 10 gallon tank little. But this guy is like bigger than a golf ball, so I don't know what to do. The tank is designed for little crabs, so I'm trying to move things around for him, but I don't have a bigger cave yet. And there's just sand enough to cover him completely and maybe a centimeter above him. Is that enough sand or do I need more? Help!
You should get a little more sand! If you can, prop your hide up a little so that he can get in it.
Anonymous said: do you know how to calibrate a thermometer/hygrometer?
I’m so sorry! I was without internet for a few days so I couldn’t answer this.
I do not know how to, sorry! If any of my followers do, please drop me a line!
I do! Here’s how to do a hygrometer: http://www.hermitcrabassociation.com/pages/calibrate.html
And for the temperature you really shouldn’t have to check it, but if you put the gauge on your thermostat and leave it for a little while you can check and see if it reads the same as the thermostat does. Someone suggested this and it really works!
Keep in mind that with a digital gauge, you will not be able to adjust anything (like it says in the link) and will just have to keep in your mind how much things are off. For example, I know my humidity reads 3% too low; so if my humidity is 80, I know that it is really 83%. So I just keep track that way. You can supposedly adjust the analog ones, but I tried and couldn’t figure it out. I would personally just know how much things are off so that you don’t mess anything up trying to adjust it. Digital gauges are definitely the way to go as far as accuracy, so I would recommend a digital gauge over an analog one!
Check it out anon!
So I found a mysterious hermit crab carcass in the terrarium today. I made sure both Onyx and Metalbeard are alive and they are. Where the hell did the third one come from?
Crabs molt! Don’t throw it away, leave it there so whoever shed it can eat it.
We have an article on molting here.
