Product description
Simple Tranquility
Seiryu Stones are often the focal point of Iwagumi aquascapes and embody a theme of minimalism and harmony. Fish and plants are added to bring balance and life to the aquascape and often used minimally. The deep crevices and rough texture of each stone creates excellent anchor points for mosses and plants.
Molded Seiryu Stone Collections for Aquascaping
Seiryu Stone is undeniably one of the most popular hardscape stones used in aquascaping. Often used in Iwagumi aquascapes, it’s deep silver-gray color and rough jagged texture creates an amazing focal point in any aquarium.
Sculpted from actual hand-selected stones, our Seiryu Stones feature the same sharp edges, detailed crevices and deep cuts found in natural stone, making them perfect for creative ledges, rock cliffs and underwater mountains.
100% completely safe for all freshwater aquarium fish, Cherry/Amano shrimp, and live plants. All stones are pre-washed and easy to clean – simply submerse, position and create a stunning hardscape! Unlike natural stone, it will not break apart, leach or cloud water. Chemically neutral, will not alter pH or water chemistry.
Get Lost In The Details
Originally from Japan, natural Seiryu Stones are now illegal to export. Our molded stones are handcrafted with the deep crevices, cuts, and texture of natural stone.
What You See Is What You Get

Lightweight and Simple to Scape With

Awesome product at a fair price
I actually bought these on a whim after spending hours looking at real rocks, particularly the WYSIWYG sections on a dozen aquarium supply sites. What ended up swaying me was that the whole kit had good looking pieces, versus the real rock kits I was looking at, which would have a few show pieces and then a bunch that werenât all that, but I still had to buy because it was a kit.I ended up ordering the 11 piece, and Iâm glad I did because the variety was great! Especially since I was still working out hardscape ideas. I end up only using 7 pieces because Iâm also planting heavy and incorporating wood. Iâm happy Iâll have the other pieces for future tanks or for scape changing.They are extremely light! Much lighter than I anticipated. I was initially worried about them not wanting to stay put once water hit the tank, but that hasnât been an issue at all. I have a busy Pictus cat that likes to root around, and he hasn’t disturbed the smaller ones.All and all, I was very impressed and very happy with my purchase. I would be interested in other rock styles in this resin format, because they are much easier to work with than traditional rock, and much easier on the tank and stand to support.I know some people were balking at the price, but considering that you know what you are getting, that more than makes up for it. I also consider my time to be very valuable so this solved a lot of my problems.

Exquisite aquarium decor, worth the $$.
Before I ordered the rocks I could tell by the pictures that they would look really good. When I opened the package I was highly impressed. You can’t find more realistic looking rocks anywhere. When you look at them, you actually feel as if you are seeing real jagged pieces of natural rock.. the weight is also nice because it appears as if they are quite heavy but they are pretty light but not light enough to float, which is good.I don’t really agree with the buyers who said that the cost is too high. The price is a very fair one for what you are getting.Overall, I am really satisfied with my purchase and I think these artificial rocks are exquisite and will make any aquarium look better with a natural look. I will be buying more. Thank you to the seller.

Beautiful Pieces!
PROS: The pieces look amazing and there are a lot of different sizes provided. There are many options to create the aquascape you want. They look so real but are light weight, so there is less stress placed on the tank.CONS: There was a strong glue smell when I rinsed the stones. My fingers were also sticky after touching them after the rinsing. I had to soak them for a few days before the smell and stickiness disappeared. Not sure why it smelled like glue.

Nice stones. Size is misleading
Stones are beautiful and high quality. However, the claim that these will decorate a 48″ aquarium is misleading. I think the stock photo is a 20″ tank. I would have to use 3-4 boxes to do a 48″ tank, and the largest stone is 10″, so not for taller tanks.

Amazing, lightweight, sinks fast
I messaged the seller, but I didnât receive any response back :/. However, I did receive the item, and it did completely meet my expectations even exceeded it for that matter. It was packaged very very well. Each artificial rock was individually wrapped and placed in its own styrofoam slot. No directions came with it in terms of setting up the stones in the way as advertised in the stock photo. However, I decided to go a different route and create a sand-fall themed tank and these rocks were perfect! So many I couldnât fit two in my 25gal. You will be very happy the rocks have amazing patterns and groves . I hope the paint does not fade overtime. Will update if that happens.

Listen to the poor reviews
Exactly what other poor reviews are saying. I bought three sets before I realized they were killing my fish. Initially it was only the rotten egg smell when opening the lid, but then I found it becoming harder to keep the water clear and environment healthy. I tried everything toward the end before finally removing them. When I picked up the rocks, identical to other reviews, black water poured out of the single hole. The rocks retain poop and toxic water that canât be removed by vacuuming or filtration. These decorations are dangerous unless they are regularly removed and rinsed or modified to open the entire bottom, like many other decorations that allow water flow. Please be aware before purchasing! I wish I listened. $300 gone.
