If you’re looking to add visual interest and appeal to your aquarium, you may have looked at different aquarium ornaments, but one of the easiest ways to achieve newfound beauty in your tank is through the addition of rocks.
Even though it sounds like an overly simple solution, rocks can be used to add color and texture to your aquarium. They can also be used to create shelters and hides, making the tank feel safer for some inhabitants.
One important aspect about adding rocks, though, is that some rocks can alter your water parameters due to the introduction of minerals into the water, so you need to know exactly what you’re putting into your aquarium.
Ideally, you should be acquiring rocks and gravel from trusted sources to avoid introducing parasites, bacteria, plants, and other undesirables into your tank. These reviews of the 10 best rocks for freshwater aquariums will help you find safe rocks to add to your tank.

The 5 Best Rocks for Freshwater Aquariums
1. Lifegard Aquatics Dragon Songpi Ohko Rock – Best Overall
Lifegard Aquatics Dragon Songpi Ohko Rock comes as a kit for variously sized rocks to fit specific tank sizes. The stones are gorgeous and have a pleasing natural look to them that will take your aquarium’s decor to the next level. They come in an assortment of sizes so that you place them in the desired configurations.
They are heavy, so you must be careful handling them. Shipping and jostling make them dusty, so we recommend pre-washing them before putting them in your tank. Otherwise, they are an excellent value for the price. With all this in mind, they are our choice for the best overall rocks for freshwater aquariums.
2. Underwater Treasures Mini Moss Rock Fish Ornament – Best Value
Too often, artificial plants look so fake and out of place. That’s not the case with the Underwater Treasures Mini Moss Rock Fish Ornaments. After all, plants do exist underwater, so it makes sense to include them with your tank’s decor. The moss is tall enough to provide some cover for small fish, making it a useful addition to your tank.
The product comes with five pieces that you can place throughout your tank. They’re small at only 1.2 inches long, although they stay put. They’re probably best used in small tanks or for a feature in a larger aquarium. Each rock is also uniquely shaped, adding interest to the space. Because of the price, they are our choice for the best rocks for freshwater aquariums for the money.
3. Nature’s Ocean Natural Coral Aquarium Base Rock – Premium Choice
You have to love the name of something called Nature’s Ocean Natural Coral Aquarium Base Rock. It’s a fitting moniker for this product. While it’s pricey, it’s real aragonite rock. You’re getting exactly what the manufacturer claims it is. The quantity varies. Nevertheless, some elbow grease and a hammer can break down large pieces.
Despite the name, the product description states they’re suitable for freshwater and saltwater. However, if you have the former, you should monitor your pH closely since the stones may affect the water chemistry.
4. Frisco River Rock Gravel
Frisco River Rock Gravel is an excellent addition to a freshwater tank that will compliment a natural look. The rocks are polished as if they were just fished out of a stream. They are smooth with no sharp edges, making them easy to clean. They are not uniform in size, making them realistic looking. You can also use them in terrariums or other setups.
They measure 0.39–0.79 inches long. That can leave some large gaps for food and debris to get stuck in. We recommend using them as a decorative element for anchoring other plants and pieces in your aquarium.
5. Current USA Dragon Aquarium Stone
Current USA Dragon Aquarium Stone would make a beautiful addition to any tank. The rocks are realistically colored and styled to give them a natural look. The pieces have lots of nooks and crannies for small fish to hide. They are also chemically neutral and suitable for freshwater and marine setups. They have some heft to them to keep them in place. You can also use them to anchor other plants.
On the downside, some edges are sharp, but that’s what you’d expect with natural rocks. However, they won’t scratch the aquarium glass. The stones come pre-washed. However, cleaning them isn’t easy, which, again, is not unexpected, given their design. The price may suggest they’re real, but they are sculpted out of a man made material.
