Securing live rock with yellow watchman goby?

[Crested]

Hey everyone, I'm in the process of planning a fluval 13.5 nano tank and plan to put a yellow watchman goby/pistol shrimp pairing and firefish in it. I was just wondering if it would be a good idea to secure my live rock so they don't get knocked over by burrowing. I heard that I should put the rocks in before the sand to prevent them from falling but not sure how strong these little guys are. Any advice is greatly appreciated :)

Rocks on the bottom then sand is definitely recommended. You cannot imagine the amount of real estate that shrimp can move. Unless its a precarious set up to begin with I don't think you would need to glue your rocks together, but might be better safe than sorry.

If the rocks are sitting on the bottom of the tank and not sand there is nothing they can do to make them unstable....unless they already are. :D I've never had any problem with pistol shrimp/goby pairs and my aquascape but I always put the rock on the bottom and then add the sand.
