These are nice (I mean, they’re stones, but they’re NICE stones)!!!
OK, these are stones. Like as in black stones that have been tumbled so they’re like polished obsidian (well not that shiny). But they’re nice. If you have the Baby Biorb, I’d pass. If you have the 8 gallon, they’ll be OK, but they’ll cover the bottom. I have the 16 gallon and these look great. I’m adding a picture. My Biorb has to be in our kitchen and we get a lot of algae, so I figured the plastic plants would go and the stones would go in, because they’re black, decorative and they’re easy to clean. So my aquascaping is as minimal as it gets. Anyhow, I hope the Feng Shui works and any negativity that my goldfish (yes, I have had goldfish for THREE years in a Biorb -and they’re doing great, thank you) and any negativity that might head our way is gone too.If you want a bag of polished rocks for your aquarium, you can’t go wrong here 🙂 Talk about an easy-maintenance addition!

Pretty
Wish there were a few more in packaging. Looks great in our Bi orb aquarium.

Anything Biorb is always overpriced
Biorb decor is always top notch, but you have to pay top dollar for them too. These are rocks, and likely you can get similar at your local pet store. For the price the package should have double the amount.

they are perfect
I am very happy, what I received is exactly what I was looking for. I got 7 stones in my pack, most of them large. Color is pure white with some veining, stones are well polished. What I paid for this I think is fair considering the size of them. I tok a picture of the whole pack in my fluval edge 6 gallons for an idea of the size.

VERY GOOD QUALITY!!!
Very good quality, and for me the quantity is good too ( I got more than 10 pieces, and great size). I think they are worth the price. Definily will purchase them again, maybe the dark color.

They’re good and bad.
These rocks are overpriced for what you get, but they are pretty. I purchased 2 bags of white and 2 bags of green. The green rocks are not entirely as pictured. None of them are the teal-green color that is advertised. Some are dark green, some almost look black, and some have a greenish-grey color. I don’t mind, though.

so soft
I don’t know about other reviews saying about the colors but i ordered white one and they came all in white and I love it. I put them in my sand aquarium with driftwood and it looks so peaceful. It’s very smooth and soft. My fishes seems to like it.

Bigger than I thought it would beâ¦
I didnât realize how big these rocks would be, but theyâre very beautiful and add a lot to the scenery nonetheless.

Je les ai utilisés en garniture dans mon pot à citronnier. Ils sont du plus bel effet met il y en a peu pour le prix, j’ai du en recommander.

Ciottoli allâapparenza naturali, belli pesanti e lucidi, di forme e dimensioni diverse tra loro, comunque in generale abbastanza grandi. Unico neo, sono davvero pochi: per riempire il fondo del Biorb Life 15 litri non sono bastati due sacchetti!!

These large pebbles are just what I needed for my aquarium. I am very into the zen, natural scapes when it comes to aquariums. I don’t like using glass pebbles or the tiny stones that most aquariums have. I found these stones gave just the look I was going for and they covered the space in my baby biorb very well. They are natural, a very nice white, and easy to clean.
