HCA: Hermit Crab Association

I went to the pet store and asked for aquarium glue (I want to glue some shells onto a plastic container so that the crabs can climb it, as well as being a hidey hut). They sold me a product called 'Reef Glue' (cyanoacrylate gel). I just want to be sure this is a safe product. Thanks!

It might not hold depending on how smooth the plastic is. Reef glue is just plain superglue, the stuff is surprisingly non-toxic when used underwater. For air breathers it has to dry completely to be safe.

Okay, so worst case scenario is that it won't hold, as long as I let it dry for a few days before putting in the tank?

Yep!

Thank you!
