This is a 40 pound assorted box. Rocks typically run in the 2-6 pound range but may be as small as a little over a pound to 8 pounds. There are approximately 12-18 rocks per box.

Four big globs arrived poorly packed

Not at all as pictured. But breaking up the chunks and building up the scape from smaller pieces was fun too. All in all more time consuming than expected - result

Great base rock

This was enough for a 75 gallon aquarium setup. The pieces fit together to make a nice formation for my cichlid tank.
