Photo of Sebastian, who is the most active.

Looks lovely! Almost anything is better than the pet store. The only thing is that you may want to make the substrate a little bit deeper. Love the name! How many do you have?

Much obliged. Sebastian is a large small and the rest are smaller, but I will probably make the substrate about 1” deeper next time. Currently I have 4, which makes the tank full.

Tank looks great! I would recommend at least 6 inches of substrate. Also, which sand is used in your substrate?

Another thing is that the pool with the bubbler looks a bit shallow, and the other pool needs to be deep enough for them to submerge in.

Play sand.

It’s deep enough for any of them to submerge. All I have are PPs so the saltwater pool doesn’t need to be deep enough for them to submerge.

I have never heard that pps don’t need to be able to completely submerge I have pps and they love to go into there saltwater dish. I would recommend getting a bigger water dish

I kept PPs for years and they never did. Now, the Straws did submerge in the saltwater pool frequently.

You also might want to get a better hygrometer, like the digital ones from Walmart or hardware stores. Even if yours is working right now, it may become inaccurate. You also might want to mix in Eco Earth to your substrate, because EE tends to hold humidity in better.

Yeah I’ll get a digital one eventually. I’ve never needed Eco Earth in the past to maintain proper humidity. The bubbler pool does that all by itself. I also live in a humid area.

My PP's love to fully submerge in both pools

Eco earth is too not only keep humidity high it is to also help burrows be stronger

What food do you feed? I see that you heat mat is below the substrate, this will dry out your substrate and trap the crabs underground

Usually fresh fruits, vegetables, and shrimp for protein. The heat mat is on the far end of the tank. I’ve actually had two of the crabs dig near and the sand was moist down to the bottom.
