Bear with me because as I read the description and read the reviews I hadn’t seen if this cave would work well for HERMIT CRABS. SO I took a chance and purchased it anyway :) I (and my hermits) could not be more thrilled with the quality and versatility of this product! Firstly, it arrived on time, well packaged and as described. But I was more impressed by the fact that it is able to be turned around to either side to make different points of entry in the substrate. This product works amazingly as cave/hide for my smaller, less social crabbies and provides an even cooler way for me & my coworkers to check in on them as needed. Thanks from the crabby community ☺️

This is a pretty cool little tunnel. I just started my tank, so I haven’t gotten to see fish in it yet
