It doesnt really look humid?

Again because I cant see any pearls of water inside this tank or wet furniture which is fatally;

Along with the proper temperature, adequate humidity in the tank is vitally important to hermit crabs. Since crabs "breathe" via gills, the proper exchange of oxygen by the crabs depends on the humidity in the air, so if the tank air is too dry the crabs will essentially suffocate. They need a relative humidity of around 70-80% and since this is so important to the crabs it is worth investing in a humidity meter (hygrometer) so you can make sure the crabs will be okay. You should be able to find one in the reptile section of the pet store. Excess humidity is not desirable either as it will cause condensation as well as encouraging the growth of bacteria and fungus in the tank.

The water dish you provide in the tank will likely be sufficient for creating the proper humidity, as long as the tank is enclosed (solid sides and top). If you need to increase the humidity level, try a fairly large chunk of natural sea sponge in a dish of water (remember to always use dechlorinated water). The sponge can hold lots of water and has lots of surface are for evaporation to boost the humidity. Have a couple of sponges on hand so you can swap and clean them frequently (soak them in very hot dechorinated water or a sea salt/water mix, then allow them to dry completely as they are a good medium for bacterial growth). If a mesh or vented lid is making humidity control difficult, the lid can be modified by covering most of the top with plastic wrap or clear packing tape.

Your tank looks incredible its a wonderful piece of work but please make sure your little babies have everything they need.

no worries... I keep their home humid... I am no styranger ta havin' herms fer pets... if ya look closer at the top pic there is a large plastic container that has 3 natural sponges in it and is filled with water so they can bathe an drink... an is a few spots along the ground, in their 'dens' and even up in one of their branches has clumps of moss.. plus I even have misting bottles ta spray their tank if it starts ta look too dry... but thank ya fer yer concerns :)

heh... an once I thought about it... another reason yer not gonna see much (if any) humidity in m'tank is that there's hardly that much differential either in or outside'a that tank lol... already live in a normally hot/humid zone an got several houseplants in m'bedroom that I water an mist regularly anyways :P

is that by your bed? if so arent you afraid of like kicking or kneeing the cage? ive put a few holes in my wall from sleep kicking lol

yes it's by my bed but no I don't have such lashings out ta worry 'bout harmin' m'tank heh :)
