I am so glad for all of the information I am finding on these forums. I did a lot of net research before I bought my hermies but now I am really taking advantage of the wealth of information available here and on the many other hermie sites.
Beware..this is a long post with lots of possibly boring (to you) details about my crabbies...so turn back now if you don't want to read my novel of a post.
A little bit about my crabitat...
I have a 10-gallon tank (hoping to upgrade to a 25 sometime soon, $$ permitting) with Calci-Sand substrate (going to be switching to mixing this with coconut fiber though) and a bottom-mounted UTH. I have a plastic cereal bowl serving as my hermies' pond and I am using Doc Wellfish (and dechlorinator or couse) to make their saltwater. The pond has 2 sea sponges in it for humidity and life preserver purposes. I have a smaller bowl with regular dechlorinated water in it which has a reptile "cave" over it to make a little grotto. They have a large piece of Cholla wood and a little ladder (the kind meant for birds) set up as a climbing peak. They also have a little decorative plastic plant, a wet food bowl, a dry food bowl, a bottlecap filled with honey and 4 empty shells. I have a thermometer/hygrometer and right now with the heat wave I have a screen lid on the tank. The temp and humidity are both steady at 80 and I have a fan blowing over the top of the tank to keep the humidity in check. Obviously the UTH is not plugged in right now. Well...that's my crabitat.
My crabbies....
Hermione is shy and very cautious about being picked up (especially now, but more on that in a minute) and Ginny is the troublemaker (there's one in every family right?
). She is obsessed with escaping from everything (her bathtub during bathtime, her drying-off box after bathtime, her crabitat, us) and is not below standing on Hermione to try to do it! They both love thier Cholla wood and spend the majority of their time hanging out there (in fact they eat more of that than their normal food I think). Ginny is a real climber [she loves clambering up my arm but gets turned upside down around my elbow (not that it stops her)] and Hermione is more introverted and skiddish.My crabbies are currently still adjusting to their new home and are a bit skiddish (understandably), they are also obsessed with escaping thier crabitat (does that ever stop and is this normal??). I am feeding them a wide variety of foods including commercial hermie food, organic baby food (just carrot so far), nori, bloodworms, honey, sunflower seeds, dried apricots, dried papaya, flax seed, coconut, cuttlefish bone, spinach, and cherries. So far the only thing they seem to be interested in at all is the honey, but I have many more ideas to try (in part, thanks to this site).
We have had one traumatic event already in my short motherhood. Hermione was being taken from the tank by my girlfriend on Saturday and slipped off her hand onto the carpeted floor.
I was so worried!!!! It's been about 4 days and she seems ok but I was terrified the fall would have ruptured her organs (it was from a height of about 4 feet and our carpet isn't thick). After that scare we have been getting along pretty well though (although Hermione is naturally a little more skiddish now). As long as nothing that that happens again I think I will be a happy hermie Mommy!
So anyways I will try to be active on this forum and get some pictures of my babies up soon!!
) save up for the biggest tank you have room for. I started with a 10 gal moved to a 20 long then I got a 55 gal and now I have a 75 gal and getting ready to set the 55 back up 
. Everything you are doing sounds great, the only thing I would check is your commercial food if you haven't already. Some have bad ingredients, you can find a safe commercial food list over to the right under Crab Care FAQ ---------------->. NarNar sells food on eBay (The Happy Hermit Crab is her store) and my crabs LOVE her stuff, sometimes I think they lick the bowl clean 
You also have very nice diet set up for them I'm sure there happy
