All-Natural Rock for Aquariums

Texas Holey Rock is one of the most popular hardscaping rocks for cichlid aquariums. The holes that these rocks are famous for provide swim activity for restless fish and help reduce aggression in the tank. One of the properties of Holey Rock is the calcium it contains. When you put it in your tank, the calcium is released into the water, and that will make your fish healthier, and the eggs they lay will be healthier. This is an amazing benefit that you can only get with limestone rock. 
This is a 30-pound display. They are clean and ready to put in your tank when they deliver, with no rinsing needed.
Please note that these rocks will raise the pH level of the water in your aquarium and are meant to be used with aquatic environments that need a high pH level.
