Best Aquarium Gravel of 2025

"I love how the colored stones glow against the black background, and even my Glofish appear brighter!"

"This tank was easy to assemble and my minnows seem to really enjoy it. Overall, a great value for the money!"

"I was surprised by the beautiful colors and how well they pop under blue light. I had to rinse off some dust, but it was worth it!"

"I ordered this to create a sediment layer for my aquatic plants and to enhance the landscape for my betta, Tatsu. After rinsing and soaking it overnight, the cloudiness was significantly reduced. I added a thin layer over my existing pea gravel in my 10-gallon tank, which was sufficient. However, I noticed a couple of things: first, the rocks don't sparkle underwater, and second, my foam filter tends to suck them up due to their small size, causing clogs. I plan to switch to a top-flow filter, but I expect cleaning will be a challenge with these tiny rocks!"

"I really appreciate this substrate for my angelfish aquarium. It’s the perfect color—rich black—and is easy to install. The price is also great for what you get. I found it very convenient for cleaning with a gravity vac, and it's just the right size for my 50-gallon aquarium."

"This substrate gives my tank a more natural look, although it did come with some brown flecks. I recommend washing it thoroughly for about 30 minutes to avoid losing fish. If you don't rinse it enough, the water will turn black, but once it settles, it looks fantastic in my betta's tank!"

"I bought this gravel for my new 10-gallon aquarium, and it worked out very well. The quality is nice, and I appreciate the mix of dark and lighter gravel for added texture. It's the perfect size for my small fish, and I'd definitely buy it again."

"I chose this fine gravel to use as a bio substrate. The color is beautiful and looks very natural. It was reasonably priced, but I had to rinse it several times to eliminate the excess dust. If you want a river bed look, I highly recommend it."

"I'm impressed with how clean this gravel was! After just three rinses, it was ready to go. It didn't cloud the water too much, and all my fish survived, which is a win in the fish world!"

"I purchased this to enhance my aquarium, and the colors are so bright and fun! I paired it with black rocks for a more subtle look, and it looks fantastic with my setup!"

"As a beginner fish tank owner, I needed something simple to sprinkle over my existing rocks. I found this product easy to use—just open the bag and sprinkle away. However, I recommend rinsing the rocks first as they can be a bit dusty. The quality is nice, and the colors are even better than in the photos!"

"I bought this gravel thinking it would be perfect for my fish tank, but it caused my fish to die within hours. After reading the reviews, I realized I wasn’t alone in this experience. I cannot recommend this product at all!"

"I love the beautiful color of this gravel. It was very clean and I hardly had to rinse it at all, making it an excellent value for my money. It looks amazing in my aquarium!"

"I got this gravel to cover plant soil and it worked great! The natural colors blend well with my plants, and I appreciate how easy it is to clean with a siphon."

"This gravel is of high quality! I was impressed by its natural look in the tank. It does have a slight smell, but it's more of a natural ocean scent. I would definitely recommend it for a planted tank setup!"

"I did extensive research for gravel that isn’t sharp because my fancy fantails are sensitive to injury. This gravel is smooth and attractive. I recommend using a turkey baster for spot cleaning, as debris is noticeable against the black."

"I’ve ordered two 5 lb bags over the last 7 months for my tanks. This gravel is the perfect size, and it hasn’t flaked like others I’ve used. It looks great under the lights in my Betta tank, and I’ll definitely reorder if I need more."

"I didn't realize how small 5 lbs of substrate is. It works well for my 3.5-gallon tank, but if you have a larger tank, remember that a 5 lb bag may not be enough. The color is nice, and I experienced minimal dust after rinsing."

"I found that the gravel rinsed easily in a 5-gallon bucket. The look, size, and shape of this substrate are fantastic, and my panda corys seem really happy with the change. The color really complements their coloring!"

"I needed a natural gravel look for my new tank setup, and I'm extremely pleased! The color and size of the pebbles are exactly what I envisioned, and the price was perfect!"

"I bought a couple of bags of this substrate to mix with what I already had. Although it claims to be clean, I found a lot of powder that needed washing off. I recommend rinsing it well to ensure the water is clear."

"I think the color is awesome and it's easy to rinse. My fish and critters are happy, so I guess they like it too!"

"Finding colored rocks can be tough, but these are more affordable than pet stores and worked great for my tank!"

"These rocks made my tank look so pretty! It was just like the picture! If you have a big tank, I recommend ordering a few bags!"

"I initially purchased this color at a store for my aquarium, and I loved it so much that I ordered a larger bag from Amazon to have on hand for other tanks. It's been in my first aquarium for several years, and the color is still vibrant."

"After switching from white to blue rocks, I can confidently say it was the best decision for my fish tank. The look is fantastic, and I’m very happy with this purchase."

"This gravel looks amazing in my aquarium! I mixed it with a couple of other colors, including a different shade of blue, and it looks excellent. It has held up well for two months, retaining its color, and my fish are happy. I hope the color stays, God willing! :)"

"I bought the 1lb blue option for my son's Betta fish, and it was just enough for his tank! It looks fantastic in the water, and my son enjoyed placing it in. I found it to be a great price for the amount provided!"

"I've used the pink and purple versions of this gravel without any issues. The colors are beautiful and dust-free, which is a huge plus. However, I recently purchased the neon yellow version, and it had a strong chemical odor that turned my aquarium water yellow. I had to switch back to sand for my betta's health."

"I was pleased with the color and quality of this gravel. It's small, but it looks great in my fairy garden. I do feel the price is a bit high for the size, but I still love the color!"
