Thank you so much for this info. Right now they’re in a 40 gallon tank with the 6” of substrate. I’m gonna go ahead and add some EE this weekend. Ever since they moved from a critter keeper to a 10 gallon to a 40 gallon they haven’t dug into the ground yet. They did disappear after critter keeper to 10 gallon for about 10 days but came back up and I’ve then transferred them over. I have linked up with someone who needed 2 crabs to be adopted about “golf ball” size. Is my 40 gallon tank too small? The 4 in my tank are about the size of ping pong balls so just slight smaller. Thanks for the advice...just want to do the best for my guys and if the adoptees need to find other home I’ll contact my person ASAP.GotButterflies wrote:Well - to be honest with you Es are very picky about their shells. They spend a lot of time modifying the insides of them, so when they do that, getting them to change...well...it takes just the right shell. They also prefer "D" type openings, although I do have a couple of Es that love their turbos.
A couple of things I personally recommend for Es: 10 gallons per crab, 10" to 12" of substrate (regardless of size)! IMO the 6" substrate minimum doesn't apply to Es. Es are avid diggers and need lots of substrate. I also recommend two proteins a day, and different calcium options for them. By following these guidelines I have never had issues with any of my Es.
So I got the substrate mix backwards. It’s more 1:5, sand:EE mix. I’m gonna go ahead and add sand. I followed the direction on the EE on how to make and the consistency is more like shoreline wet. Not dripping but definitely moist. I’m hoping dry sand will make it where I need it to be without having to start over. Right now my E crabs are just sitting there. I mean they just sit on their branches and chill. When I turn the light off they move around and I find them at a different spots in the morning. Reading from the info pages hermit crabs are mostly nocturnal so I don’t think I should be working right? Their tank is at a steady 80* and humidity 75-80 with a bubble stone. Food is changed everyday and given variety. Anything else you can think of that I can improve upon. I’m doing the last touches of my tank set up and will post a picture soon.GotButterflies wrote:IMO Es don't do well with overcrowding. Purple Pinchers are okay with it, but Es...not so much.
Is your substrate just EE? Is it moistened to be sandcastle consistency? I personally love the 5:1 playsand to ee mixture. I mix mine with dechlorinated msw.
