A dramatic, textured stone for natural aquascapes and terrariums.
Darwin Black Lava is a jet-black volcanic rock known for its rugged surface, deep crevices, and striking contrast. Ideal for use in aquariums, terrariums, and vivariums, it brings bold texture and depth to any layout.
Naturally porous and rich in minerals, this stone supports the growth of beneficial bacteria—helping to create a stable, bioactive environment. Its surface also provides excellent grip for mosses and epiphytic plants like Anubias, Bucephalandra, and Java moss.
Lightweight yet solid, Darwin Black Lava works especially well with wood in ryobokustyle aquascaping. It’s also a top choice for high-humidity habitats thanks to its ability to retain and release moisture effectively.
And because it’s inert, it won’t affect pH or water hardness—making it safe for sensitive aquatic species.

Our Delivery Promise To You
If you choose Express Delivery, we will replace any plants that are damaged due to delays. Express Delivery is a fast, trackable, and reliable option with a one hour delivery window. It also ensures that the plants will arrive in the same condition as when they left our facility. If you choose a different postage option, such as Tracked 24 or Tracked 48, you will not be covered for any damages due to delays and will assume the risk yourself if the plants do not arrive in good condition. Express Delivery includes an insurance policy, which may cost more but provides added peace of mind.
Your plants will be wrapped with recyclable Honey Comb wrap - sounds cool because it is :). It interlocks which means we don't need to use tape either, reducing our impact on the environment.
Not only is delivery fast with DPD Express but it's also green as they offset all the carbon their vehicles produce. Guilt free delivery which we're very proud of...
We guarantee you'll be happy with your order. But if you're not, please contact us so we can resolve. We are 100% here to help and will always do our best to resolve any issues - that's a promise.
