100% natural stone that is safe for your aquarium and has been sourced, washed, and packaged by our family owned business in the USA. The color is a deep grey. Each package is a mix of stone from 3 to 5 inches (some stones may be slightly above or below this range)
AQUARIUMS – Ideal for aquascaping planted, fresh or salt water aquariums, paludariums, as well as biotope, Iwagumi, Dutch, nano and beta tanks. The deep grey of this stone really makes the plants and tank inhabitants pop! Create cliffs, caves, mountains, berms and walls. They can be laid flat, stood on end or placed at an angle with support. Use with our larger pieces, smaller stone and aquarium gravel to create a realistic scene. This is a great size to attach to medium/large sized driftwood to keep it from floating
REPTILE ENCLOSURES – Perfect in terrariums, vivariums and other pet enclosures. These stones naturally hold heat for reptiles or other heat loving pets. They can be glued together to create caves, cliffs, berms, walls or used for smaller reptiles/pets as climbing, basking stones or feeding stations. Use with our larger pieces to create an attractive and natural environment for your pets
MINIATURE – Perfect for creating walkways, benches, walls, steps, archways, caves/caverns, ground cover (patio), water falls and much, much more in dioramas, miniature or fairy gardens, mossariums, miniature models and model railroads. We offer several larger and smaller sizes to create a seamless realistic hardscape. Great for mosaic art, too
As a natural stone, there may be some white quartz veining or brown surface discoloration. These beautiful variations add a natural uniqueness and interest to the stones. Use aquarium safe glue or epoxy to secure all your creations for the safety of your inhabitants

Beautiful Slate for aquariums!
Love this Slate for my Aquariums!! The stone arrived in perfect condition and is absolutely beautiful. There are all different sizes. I havenât put it in my tanks yet, but thereâs enough to put in a large tank or use some of the pieces for multiple 10 -20 gallon tanks! Iâm going to make a corner cave for my clown loaches and I will still have a lot left for my other tanks!! Great product and I highly recommend!

Beautiful Stones
These stones are really nice and exceeded my expectations. I included a picture of what the 5 lb. bag looks like wet and dry.
Amanda –
Perfect!
These are exactly what I wanted. I am upgrading my ADFs 10 gallon tank to a 20 long. I wanted more visual interest plus more hides in the new tank alongside all the plants and driftwood. This ended up being exactly what I needed! There were more pieces than I expected too, which was a great. Very nice variety of shapes and sizes too. They were a little dusty, but thatâs to be expected. Just rinsed them and theyâre fine. They are still wet in the photos, so this is how dark they will be when the tank is full. If I could give these more stars, I would.

Nice mix of stones
This was a nice mix of rocks to use in my vivarium. Very dusty upon arrival, but a quick scrub in the sink and they look great! I will note that these were on the smaller side of these dimensions, with only two of them actually being 5 inches, and they were both long and narrow. Still, there was a decent variety of thin and thick rocks to work with. I do also wish the smaller quantity wasn’t such a steep price compared to the bulk option.

Thick, beautiful and ph neutral!
I got the 5 pounds of 3 – 5 inch slate pieces. They came nicely packaged in a box and none were broken. There are enough pieces for me to aquascape 2 nano tanks (such as 2 9 inch cube tanks or 2 standard 2.5 gallon tanks). A few have some slight chop marks but they’re not obvious.A few of my pieces had white and clear veins (likely quartz) which I think is a nice bonus and adds interest. If your pieces bubble let them sit for a while in water, mine bubbled initially but it was air pockets not limestone. Completely ph neutral and I would know since I keep shrimp that like low ph of 5.5, definitely nothing coming out of these!None of the pieces are overly thin or square so don’t expect that. If you want to make the slate bridge I’ve seen a lot online, you’ll probably want the next size up to get a long piece.I got 2 of 5 inch rocks, 4 of 3 inch pieces (palm sized) and 2 pieces about half of the palm of my hand. The thinnest piece is about 0.5 inches and the thickest about 2 inches. I broke one of the smaller pieces in half to work better as accents. These worked very well for an iwagumi aquascape.

USEFUL STONES FOR MANY USES
PRODUCT IS VERY GOOD. ENJOY THE SIZING THAT CAN BE USED IN DIFFERENT WAYS I, IN PARTICULAR HAVE FOUND A FEW USES FOR THE STONE OUTSIDE OF A FISH TANK.

fair price, good selection, excellent rocks
Couple of the reviews had me worried – but it was perfect. Good size pieces, quickly shipped, packaged nicely. Im going to leave the same review on all of the sizes. I bought 3-5, 5-7 and 8-10. All 3 sizes were very distinct. Good shapes. Not lot of “flat machine cuts”. overall very happy. unfortunately, 10-12lbs only gets you so far so you’ll have to get a few shipments! Cheaper than LFS, and honestly better selection which was the real deal breaker for me!

good

Great little selection of slate, looks beautiful in my natural themed planted tank. I used aquarium sealant to glue them together, worked like a charm. My African dwarf frogs, Ramshorn snail, and betta all seem to like it! Will probably order more so the frogs can have even more places to wedge themselves into. Thanks!
Melissa –
Ordered these for an aquarium. Lovely assortment of rocks between 3-5 inches in length. Rinse them before putting in to your tank as they are a bit dusty.
Claude de Montreal P,Q, –
belles pierres, mais serais mieux si il y`en avait de plus grandes pour un aquarium de 65 gallons, pour le prix il me semble juste (surtout quand on habite le centre ville, c`est pas évident a trouver). Je rachèterai probablement si le prix ne monte pas trop.
