Best Aquarium Décor Rocks of 2025

“I think these rocks are gorgeous; I ordered 7 pounds and received two large rocks and a smaller one. They will be perfect for my shrimp tank. They do arrive dirty, so make sure to clean them well, but overall, I’m very pleased!”

“I purchased the 4.4 lb set for my 10 gallon aquarium, and it was more than enough. I received three pieces, and I used two. I glued an Anubias plant to one, and it held perfectly! They have added natural beauty to my tank, and I get many compliments on them.”

“The rocks were as expected; I received one large, one medium, and a few small pieces. After rinsing them with a power washer and soaking them, they really brought out a wonderful orangey color that mixes beautifully with my black gravel. They were packaged well and arrived without damage.”

"I found these rocks to be awesome! I used them in my 20-gallon high tank with freshwater angelfish. After rinsing them thoroughly, I let them sit with Seachem Prime for 24 hours before adding them to my tank. The color is great, and I received many pieces to create my structure!"

"I was excited to receive this 10lb pack, which contained about 8 nice pieces of rock. After washing them with RO/DI water, I placed them in my sump and display tank. I can't wait for the coralline algae to grow on them—definitely the best value for dry rock!"

"I bought this for my 22-gallon long nano reef. Contrary to some reviews, I pulled out 13 pieces, which was a pleasant surprise. Though there was some rubble and dust, I might glue the small pieces together for structures. Interestingly, there was absolutely no ocean smell, which was unexpected."

"I received a decent variety of sizes in a gorgeous slate grey color with some white veining! The rocks were in great shape, and I was able to select 3-4 awesome pieces for my 5.5-gallon shrimp tank."

"While the delivery took a bit longer than expected, these rocks were absolutely worth the wait! I placed one in my terrarium and got comments like, 'They look like miniature mountains.' However, I noticed that several rocks had straight slices not going all the way through. I'm not sure if that was intentional or not."

"I'm very pleased with my purchase! I ordered the 44lb set, which provided a great variety of sizes. I love the way the rocks look when wet; they get significantly darker and have a cool aesthetic. They stack immaculately, almost as if they were designed to do so."

"I bought the big box and found awesome pieces with deep grooves! A few were chipped from shipping, but I expected that. They're helpful for creating a natural look around my rocks. Overall, I'm very happy with my purchase."

"I usually don't leave reviews, but I just have to share how much I love these! After placing the small box in my tank, the rocks looked great and my fish adore them. They create plenty of hiding spots. Just be cautious; some edges are sharp for fish with delicate fins."

"These rocks exceeded any I’ve seen outside. I was truly amazed by how they transformed my terrarium. The slate gray color is exactly as shown, and it’s fulfilling to purchase something so natural and beautiful. Living in Florida, I appreciate that these rocks are imported. You don’t need to live here to enjoy them; just buy them!"

"I received two stunning dragon rocks that look gorgeous. After a gentle wash, they were perfect for my tank. They didn’t cloud the water, and I’m thrilled with how they fit into the aquarium."

"These rocks arrived a bit dirty, but after thorough rinsing and spraying, they turned out beautiful! I love their rusty brown/orange color and the nooks and crannies. The size is just right for my tanks."

"I was a bit disappointed to receive one large rock instead of a mix. But I made it work by breaking it into smaller pieces, which actually turned out great. It adds a nice touch to my aquarium!"

"I am very pleased with my purchase. Fast delivery to my door at the same price as my local store is a huge plus. The dragon stone was dusty as usual, but after rinsing it thoroughly, it looked perfect. I appreciate the excellent variety of sizes and shapes."

"I ordered the 20-piece set and was delighted with the different shapes and sizes of the stones. After giving them a good scrub, they turned out beautifully. I was worried about the cleanliness, but now I'm excited to rescape my tank with these!"

"I used these rocks in my kids' aquariums, and they absolutely love them! The stones give a natural and unique touch to the tanks. I boiled the rocks first to ensure they were sterile, and they arrived in great condition with minimal breakage. For the price, it's a fantastic deal!"

"I think the color is stunning, especially when in bright light!"

"After a year, my stones still glow beautifully outside my cabin!"

"I placed them in the bird bath, but sadly, they did not glow at all."

“When I received my order, I was initially concerned because they looked a bit crumbly and were light gray. However, once I placed them in water, they transformed into a dark gray that enhances my fish tank beautifully. Although my tank became a bit cloudy at first, it cleared up quickly. My fish seems to love it, and I haven’t had any issues since! I did find it tricky to keep them standing because the water pushed them around, but after securing them, they’ve stayed upright. They are smaller than I anticipated, but overall, I’m pleased and giving it 5 stars!”

“I ordered these hoping they would serve as a basking spot for my adult bearded dragon, but to my surprise, they turned out to be quite small. They might be suitable for a baby beardie or a smaller reptile, but they just didn’t meet my needs.”

“I have an ackie monitor, and I decided to glue these together with silicone. They look great and get hot under the lamp, making them a perfect addition to my setup!”

"The rocks arrived undamaged and double boxed. They are large and high quality, perfect for my scorpion tank and shrimp tank. They were a bit dusty, but washed off easily. I received six rocks a day earlier than expected!"

"I found the description misleading; the rocks were not cleaned at all! I had to spend hours soaking and scrubbing them, which was frustrating."

"I was disappointed with the amount I received for the price. The pieces were also smaller than I expected."

"I wanted a more natural tank environment, and these rocks look amazing. The rocks were as described and the right size for my tanks. I was able to make a couple of rock formations. I highly recommend these rocks!"

"I was really happy with this rock. It arrived clean and beautiful with some light sparkle. The pieces were the perfect size for my small terrarium. I would absolutely buy it again."

"This slate is a perfect addition to any aquarium. I used it to hide a bubble wand at the back, but it has so many potential uses. The description was very accurate, which is rare on Amazon. The slate was clean and well-packaged, and the seller offered a very fair price. I am beyond impressed!"
