Inactive hermies

Post by Beenzsouflee »

Hello my names Heather and I'm new here. I just got some hermies for my daughter and I want to make sure they are happy and healthy. I haven't noticed them eating or drinking and I've read the tricks about smoothing the sand to see if there are tracks, and I understand they are nocturnal. They have been hiding under the long flat decoration in the back half buried in the sand and I'm concerned that they're not comfortable. Her father bought them painted shells which I refused to give them, so I'm getting some natural shells today as well as some chola wood. Any other tips would be appreciated its breaking my heart thinking that they are uncomfortable in some way. Thanks!

It's very common for new crabs, especially ones purchased from a chain store, to be inactive for a couple days up to a few weeks after purchase. They go through a lot of stress from being taken off of the beach to the store. I have always seen my new crabs burrow down, even though I refrain from buying from local stores. They do this to relieve stress, some will even molt during this time, which is common.

You said your substrate is wet, it should be mixed with either marine saltwater or regular freshwater, that has been dechlorinated, to make it sand castle consistency. The brand of saltwater that you have listed is incorrect, it will not provide them with proper water for bathing and drinking, that is meant for aquarium fish illnesses. Instead, a lot of people use and recommend, including me, the Instant Ocean or RedSea brand of salt for making saltwater.

The temperature should be at least 78 to 80 degrees Fahrenheit, small gradual fluctuations are best through the night time. The humidity should always be at least 80.

I am not seeing images of your crabitat, could you repost them?
