Hermit Crab Ladders?

[bg2311]

Does anyone use something like a ladder for their frag racks so that the hermit crabs can climb up and do their thing? I've considered 3D printing one for them but I could also just cut a strip of egg crate out and attach it with zip ties so it hinges easily. Our frag racks are elevated on 1" PVC posts and are multi-tiered which are difficult for the crabs to climb. The snails of course have no problem. Interested to see if anyone has added climbing ramps/ladders.

I 3D printed my frag rack legs and the hermits have no trouble climbing them, so if you want the hermits up on the racks, it’s another option. I’m always impressed with what they are capable of climbing. Your solution could be as simple as roughing up the pvc legs you have with some sandpaper among some of the others you have suggested.
