It is a 20 gallon on bottom, 20 gallon on top!

Thank you so much!

PS it is hard to tell in the photos since I am only taking pics from the front of the tank but the crabs have lots of walking room on the substrate / ground. They also have been MUCH more active now that the tank has a lot do stuff going on. I think they feel safer to explore and move about knowing ...

I’m happy with my crabitat and so are my crabs so thought it might be fun to share some photos! https://uploads.tapatalk-cdn.com/20230811/ec0f7dcec44ce88f941356f67bab2c75.jpg https://uploads.tapatalk-cdn.com/20230811/4bc64c8274e6d4d5a2a7443d4c8c22b9.jpg https://uploads.tapatalk-cdn.com/20230811/a104...

Hi everyone! Quick questions for those with more experience in this area than I.. in terms of foraging, what are some staples that you always keep around the tank? I’ve learned many people have different suggestions, curious to see what you folks have on here! When you leave these foraging items out...

Lady’s Thumb grows abundantly around New York, it is safe for humans to eat (leaves and seeds) and my family’s rabbits love to eat it. It’s very easy for me to forage from the backyard where there is no chance of chemicals. Do you think it is safe for my crabs? I don’t see it on any of the safe food...

Update! The infestation seems to be under control. Sealing up the tank for two days helped stop them from coming OUTSIDE of the tank and I found a trick on YouTube - lining the outside of the crabitat tank entrances with Vaseline (I used aquaphor because that is what I had). The mites that try to ex...

Grain mites need two things for their population to explode - a steady food source, and humidity higher than 50%. Unfortunately so do hermit crabs. You can definitely battle against them and while it's almost never a clean sweep, numbers can be controlled. Food sources - not just what the crabs are...

I know this is unrelated to what you are asking, but I feel that it is important for me to note. Most crabitats are the same weight as regular fish tanks full of water, if not more (depending on substrate used and how much substrate is in the tank). The thing your tank is currently on can not proba...

Hi everyone, I am not sure what to do! My crabs and their crabitat have been my pride and joy and most rewarding project. I have 3 small PP’s and 2 medium in a 20 gallon base tank with a 20 gallon topper. Initially, I had the three tiny ones in a 10 gallon, but when I learned I was obtaining two mor...

P.S: just another fun update… now all of the crabs are obsessed with the wheel and sometimes even use it two at a time and take turns spinning each other!! So cute! Are there any other toys that stimulate crabs as much as the wheels?

Thank you for the encouragement !

Hi there
Have you had any luck finding an adopter?

Did you find someone to adopt it yet? How large is it? Poor little guy must be lonely!

:crabbigsmile: A fun update!!!! I moved my 1 crab that was semi active and not buried underground to a second tank, set up with all the needed works plus a lot of fun additions; tall cholla logs, moss pit, shell shop, pools, multiple hides, etc. Humidity and temps right in the optimal zone, along wi...

Thanks for the reply! That’s what was puzzling me, there are other hides that are on top of about 6 inches of substrate so I thought it funny that they are all piling into the same cave - but that’s a good point. They may each have separate burrows starting from the cave entrance that they are all i...
