Black Dragon Rock (also known as Dark Dragon Stone or Ohko Stone) is a highly popular sedimentary mudstone used in aquarium aquascaping for its unique, scale-like texture and deep, rugged coloration.
Key Features
Aesthetic Appeal: It features a scaly, porous surface with intricate crevices that mimic natural mountain ranges or dragon scales.
Water Safety: This rock is inert, meaning it will not alter the pH or hardness of your water, making it safe for sensitive fish and shrimp.
Plant-Friendly: Its porous nature and deep holes provide excellent anchoring points for mosses and epiphytic plants like Anubias or Bucephalandra.
Practical Benefits: The natural holes offer essential hiding spots for fry and small shrimp.
Maintenance Tips
Before adding Black Dragon Rock to your tank, it is essential to wash it thoroughly. Because it is a mudstone, the crevices often contain dried clay or soil that can cloud your water if not rinsed out.
