Pisces USA Seiryu Aquarium Rock, 17-lb bag

My aquarium rock set came in several sizes and shapes. White,gray and white and gray mix. Big and small sizes, I had a lot to choose from and I'm very satisfied with purchase. Thank you Chewy!

I've ordered these twice now, slowly working on building up my 75 gallon cichlid aquarium. I was pleased with my first order...beautiful shapes. A couple weeks later I ordered an other bag. I was INCREDIBLY happy with this one. They're rocks, they're not going to be consistently, exactly the same so I don't expect my 3rd order to be what my second one is but I'm sure I'll still be just as happy.!

Purchased about 60lb of rocks from another source they were more pricey, but I saw pictures of the specific rocks all medium to large size. After reading a few reviews of the stones I figured I'd get a bag full of smaller Seiryu stones that I can use to. Not even close. Two of the stones making up about a little more than half the weight were not even close. They were rounded rocks made of thin layers with flecks of quartz in them the rocks. They retained their pale grey color even after an acid wash. The two rocks were also as heavy as my other seiryu rocks much larger than them. The rest of the rocks except two of them looked like seiryu stone, but may have just been very poor quality Purchased about 60lb of rocks from another source they were more pricey, but I saw pictures of the specific rocks all medium to large size.

The rest of the rocks except two of them looked like seiryu stone, but may have just been very poor quality. After the acid wash they did darken as expected but most had very little marbling and some none at all. They also were very crumbly and chalky. Two of the rocks were fairly nice though with a nice shape, although among the smallest of the rocks both around 3"x 2" in size. Nice rich dark color almost black with nice white veins that didn't' feel like if I left them in the aquarium for a week I'd crush them with a siphon during a water change. The review isn't a reflection of Chewy but the Pisces rocks. In the end you get what you pay for I guess … more

I'm so happy I purchased these rocks. They are so beautiful, heavy and come in different sizes. I got about 2 big size rocks, 2 medium and multiple smaller sizes. I didn't use all if the smaller ones in my tank but I did place the extra pieces in my garden. I would recommend this item for a simple but expensive look for your tank. They are a grey slate color and are each unique in shape and look.

I ordered two. I was under the assumption they would look like the color in the photo which is a light grayish to dark gray. I receive both shipments at the same time in the same chewy box. Inside we’re two smaller boxes. one was light gray the other rocks were dark orange/brown. They did not come nicely packed as indicated in the photo they came in a big plastic bag in a box. Some were broken. They are good quality and I can make it work. I was not expecting two dramatic different colors of rocks. I’m sure my cichlids won’t mind. :) this a pic of them wet. Still very nice.

I love these rocks! I have a ten gallon planted tank and really wanted to add some rocks. After researching different kinds, and checking what was available in stores, I found these which were a great deal compared to most pet stores and I did like the look in the pictures. After receiving, I'm even happier as there was a variety of sizes and the color of the the rocks is beautiful! It's a great slate grey with marbled streaks of white and pink. My fish and shrimp are loving the extra hiding spaces the rocks provide as well.

I selected this because of the price honestly. I needed rocks to add to my Mbuna tank. These worked perfectly. There was one really large piece, 3-4 medium pieces and several smaller ones. Enough for me to create caves for them. Very happy with these rocks.

I assumed from all of the photos, descriptions, I was getting 5-10 large rocks. I received 32 small stones, 4 larger than my hand. I will have to adhesive together or just lay flat on the ground, not the "wow" factor I was looking for.

These rocks look amazing. I got one big rock, 3 mediums sized, and a bunch of small-medium sized ones. The price is great too compared to other retail stores.

I looked all over the web for rock for my aquarium. This was by far the best buy for the weight. I bought two bags for my 55 gallon aquarium. Also, the package was shipped and at my door step THE NEXT DAY!!!
