LR rubble

[Mr31415]

How much rubble should I put in the tank, and how big should the average piece be? I have put in a couple - some the size of a child's hand, and my small (3-4") mantis amazed me as he pushed those "boulders" to his nest.

When your mantis runs out you should add more within a couple of weeks IMO (kinda like jawfish)

I get branched live rock and break it up with a hammer and screwdriver into pieces approximately 3/4"-1" long.
