New crab buried itself within hours of being placed in tank

Post by HermieFam » Mon Jun 19, 2017 9:41 am

My family and I just returned from a trip to Florida with 4 hermit crabs for two of our sons. (I blame my husband completely. 8) ) On the 10 hour ride home, I did a lot of research on the internet and learned we were nowhere near properly prepared for this journey. We rushed to a couple of local pet stores yesterday and got a 20 gallon tank with a screen lid, a hiding cave, a beautiful piece of mopani wood, a water pool, 3 new shells, and some grapewood. Believe it or not, both stores were out of thermometers! Yikes. We set up the tank with a 5:1 sand/EE mixture moistened with saltwater. (The only aquarium salt they had was for freshwater fish, however I read a few posts which said to use 8 teaspoons per gallon instead of 1/2 teaspoon.) I booked the new shells, wiped down the tank with hot distilled water, cleaned the bowls, etc. before placing in the tank. We set up one saltwater pool and one freshwater pool using distilled water. We have ordered other necessities from Amazon which should arrive tomorrow including uvb light, day and night bulbs (25W), sphagum moss, digital thermometer/hygrometer, light timer/thermostat. I am aware it is best practice to establish a consistent, ideal temp and humidity in the tank before placing the crabs, however all we had was the horrible carriers we got at the souvenir shop in Florida which they had already been inside for two days (including that 10 hour car ride I mentioned earlier). Needless to say I know they had to be stressed to the max and I wanted to get them out of there as quickly as possible. We placed a small space heater by one end the tank which has adjustable temp and built in thermostat so it turns itself off and on. I misted the tank with distilled water and placed plastic wrap loosely over the screen top to try and keep the humidity in. We keep our house around 68 at night and 72 during the day, so I know the tank isn't too hot for sure, however, I am sure it could definitely be warmer.

One crab "Pinky", headed straight for the saltwater pool and sat in it for about 4 or 5 minutes straight. I felt so sorry for him! "Spiral" sipped on some freshwater for a minute or two. They both walked around a little and climbed on top of the cave. It was very fun to watch! The other two "Ghost" and "Rocky" seemed more quiet. Neither wanted water or food (I had provided some grated organic carrots, a couple of torn spinach leaves, and some dried shrimp.) Instead they hid either in the cave or under the mopani wood. Rocky and Spiral met for the first time when Rocky attempted to enter the cave where Spiral was blocking the entry. They were clicking and touching their feelers and it almost seemed to be getting a little heated, however Rocky (who is smaller) pushed his way past Spiral and got into the cave. Rocky came out again last night and was standing on the extra shells. However, this morning he is missing. I know he buried himself but I have no idea where! I was assuming there would be a little hole or something, but there is no evidence that any digging occured anywhere.

My question is whether or not this is normal. Is Rocky molting? Is he sick? Is it just from all the stress? I know I shouldn't dig him up, but I'm just wondering if I need to do anything at all? How long should I wait before trying to find him? My fear is the stress may have been too much for him. After learning more about these little guys, I'm already getting attached to them. I want them to be as comfortable as possible, but I know despite my best efforts, their crabitat still isn't ideal yet.

I'm not sure if this matters, but from what I have read, I'm pretty sure Rocky is a Purple Pincher. Spiral and Ghost seem to be Ecuadorians. Pinky may be a Purple Pincher but his coloring is more pale than Rocky, however his legs have a lot of the little hairs on them and his big claw is very purple.

Could be some post purchase syndrome, which happens a lot with crabs bought from stores. Just keep em happy & keep an eye on them.

Congratulations on your new crabbies! I'm so proud of you for doing the proper research for your new pets right away! It's completely normal for them to dig down right away to destress or even molt. He is not necessarily sick, probably just stressed. Never dig them up. Let them do their thing. You don't need to do anything other than focusing on setting up the best environment for them. Assume everything is OK. They can molt for several weeks or months at a time. Also, they are nocturnal, so you might not seem them much. The only reason to be concerned is if you start smelling an AWFUL dead fish smell.

There is one other possibility has gives me a small bit of concern. How tight is your lid? Crabs are very agile, excellent climbers, and very strong compared to their size. Some are very houdini-esque. You need to have something heavy on top of the lid to prevent escapes. Even if you don't have any climbing accessories that lead directly to the top, they can climb the silicone in the corners.

If you'd like us to double check your crabitat set up, you can fill out the Emergency template found in the Emergency forum which you can copy and paste here. A picture is nice too, but not necessary. That would give your crabbies the best possible start in their new home! :)

Hello! Welcome to the HCA!!! :butterfly::

I commend you for doing your research!! :) A few things...the salt needs to be saltwater to mimic the ocean, you need a product called Instant Ocean. Aquarium Salt for freshwater fish just helps keep fish diseases in check. It doesn't give the hermit crabs the essential trace elements the hermit crabs need.

PLEASE NEVER EVER DIG UP A CRAB!!! Crabs bury themselves for several reasons. To chill out, (de-stress), cool off, to molt, and to explore. Digging up a crab almost always ends up disastrous.

Cover your screen lid with press n seal or saran wrap to keep moisture in where the lights are not. Humidity is extremely important as they need the humidity to breathe with their modified gills :)

Thank you! We currently have a screen lid which has small knobs you turn to lock the lid in place, so it is definitely secure. Once we get our lighting situation set up, we will reevaluate this current lid to make sure everything works together safely and effectively.

Rocky came out from under the sand in the middle of the tank. He walked around for a minute and proceeded to dig right in the front corner of the tank. Lol! At least I can see him now.

Great! Oh, I forgot to mention that when they bury themselves that sometimes it is not obvious where they go down because they backfill their hole.

Congrats on your new pets! Much like you've described, i had no idea how much care hermit crabs required when we got ours from a free craigslist ad in February this year. I was so glad to have found this message board. Everyone here has been very helpful.

I can only mimic what others have already posted. The only thing that I would add is that the use of heat lights will really zap your humidity. We started off with an infrared heat bulb as well as a compact fluorescent (which has the daylight sunlight rays, but does not get hot). The compact fluorescent was very expensive. 25 bucks for a 5.0. We ended up not using the infrared heat bulb and replacing that with an ultratherm under tank substrate heater, mounted to the outside back glass of the tank. The infrared heat bulb was keeping the tank from staying as humid as it needed to be. The ultratherm was a bit pricey but has been a lot more effective at maintaining humidity and heat. Before we purchased the ultratherm we were also using a space heater. This actually worked out very well in the interim, before we could afford the proper heater.

I can definitely sympathize with you about the crab burying itself and being worried. Just assume that everything is okay because they can stay down for several months. I've actually started writing it on the calendar so that I can remember which crabs buried themselves and how long they have been down.

Hello,
I have the same thing happening with one of mine. Two of mine are molting but one buried itself so quickly, I didn't have time to isolate! I'm just keeping an eye out and hoping for the best.
When I got them into their new crabitat, they were so happy! Digging and tunneling and climbing and playing etc. I wish I could have gotten all 100 or whatever they had in that beach shop :(
