【Nature’s Artistry, Each Piece Unique】100% natural Seiryu rocks come with gray – white textures and intricate gullies. Their natural appearance can enhance the beauty of any aquarium space, adding an artistic and natural touch to aquascaping and aquarium decor, making them excellent aquarium hardscape rocks. PS: The color of Seiryu rocks may show certain differences in dry and wet states. The color will be a bit darker when wet.
【Aquarium-Safe】Natural Seiryu rocks are composed of various minerals and are stable in water. They do not release harmful substances. Although they may slightly increase the water hardness, there is no need to worry as it has little impact on fish, shrimp, and aquatic plants. It is recommended that you turn on the filtration cycle or change the water regularly to easily solve this problem.
【Beautiful Aquatic Scenery】Combined with wood or aquatic plants, Seiryu rocks can create an infinitely rich aquascape. You can take Seiryu rocks as the main body and match them with uniquely shaped driftwood to create a picture of ancient driftwood accompanied by steep rocks. Then, dot foreground plants such as dwarf baby tears and hairgrass around to form a three – dimensional underwater world. This combination allows you to fully unleash your creativity and create a unique aquascape that meets your pursuit of natural beauty. At the same time, it can stimulate the exploratory nature of the fish and provide them with an interesting habitat.
【Durable & Low-Maintenance】Seiryu rocks have a high density, good weather resistance, and compressive strength. They can maintain their appearance in various environments and are suitable for long – term use. Moreover, Seiryu rocks are easy to clean and shape, and can simulate different natural landscapes, such as mountains, waterfalls, and water flows, adding more natural and visual effects to the aquascape. PS: Each rock has been pressure – washed, but due to the many gaps in the rocks, it is inevitable that they will get dirty during transportation. We strongly recommend that you thoroughly clean the rocks before putting them into the fish tank after receiving the goods.
【Multi-Scenario Application】Widely used in aquariums, aquarium decor, ecological boxes, reptile boxes, amphibian enclosures, courtyards, bonsai,flower beds, and interior decoration to increase the layer of space and artistic atmosphere. Whether creating a Japanese-style water landscape or simulating a natural mountain-water scene, Seiryu rocks are a perfect fit.

Great Size for Nano Tanks.
First time working with these stones and found them to be pretty good for my Nano tanks. Very east to attach plants and my shrimp seem to like picking through them. Just make sure that you wash them off good since some have a little dust on them.

Decent collection of seiryu rocks
These comes individually wrapped in thin bubble wrap. Slightly dusty but youâll want to wash them anyway so not a big deal.These seiryu rocks are a decent collection. I got the 4-6â at 6.6lbs and got six pieces which were all pretty similar in size. I wanted some thicker ones and thatâs what I got so I was happy. However, itâll be random so itâs a risk you take.If you look at my photos, you can compare to another seller I bought from. Bottom is this Hygger seller (not cold are darker because I just washed them before the photo) and the top is another seller ChaoLeHo which was advertised as 2-7â at 10lbs. It was about $7 more but it had more variety in size, but nothing too thick like this Hygger one.So all in all itâs always a risk to see what you get and if you like them. Itâs always best to see what youâre getting but sometimes you might not have the luxury of buying at a LFS. I just took a risk because itâs a lot cheaper online than locally for the amount of rocks I need.

Good variety in size
(My opinion of them is when they are dry, I did not use them in an aquarium I used them in a bioactive tank)Not exactly what I was expecting, does not look like the picture but half of the rocks were decent enough to use. The ones I kept were a nice consistent color and had some white going through it and the ones I didn’t keep looked like something I could find….. With that said I did order them twice because I was hoping to get more of the ones I liked but it was 50/50 again

Satisfied
Nice selection of rock at a fair price per pound. The pieces have good color and unique shapes, which really add personality to the tank. Overall, Iâm pretty pleased with the quality. Just a heads-upâthis type of stone can affect your water parameters, so make sure to do your research and confirm itâs suitable for your aquarium setup.

Large, dark, rectangular rocks. No visual interest.
I expected more variety in shapeâbut wound up with 3 large rectangular rocks that arenât particularly visually interesting. Not what I expected but theyâll do as a substrate barrier. Much darker in color than pictured, larger pieces than expected. Can probably find a better value (and the ability to pick the rocks you like the shape of) in store.
