"By the Pound" means you are choosing the weight of your rock.
Ex: Qty 5 is 5 Pounds of Rock, NOT 5 Rocks.
Selling individual rocks is impossible due to the fact that every rock is unique in size/shape/weight.
Base Dry Rock - 20 lbs equals about 7-10 good sized pieces. This rock is nice, not quite as porus or white as Marco Rock but similar in nature.
Clean lots of swim-throughs and fragging surface area Some rocks may break during shipping, this is normal. Natural feathering processes form the fantastic shapes of the Rock by the erosion and pitting of limestone over the course of eons. It is clean and safe for marine, reef and hard water freshwater aquariums such as African cichlids.
