"Thank you!"

I wanted a dark rock decoration for my 5 gallon. It took about a hour to clean the rocks off. I couldn't find these at any of the aquarium stores near me, chain or independent. The only thing that was frustrating was the wait time for the shipping. Since it's 17lbs obviously you're going to get mostly small rocks. If you are still questioning your purchase please re-read the headline. I also placed one or two inside her bathing dish to help her climb in and out better.

biOrb 46053 Final Thoughts

"This stone is gorgeous."

They are making these by sloshing resin around in a mold, so it's really thin. Other fish may not like the ph change. It took about a hour to clean the rocks off. Stones were perfect for my 5 gallon planted tank. Waiting in my second bag as I'm typing this. Great stones, came with 3 various sizes for the 5 lbs option. I used these for Aquarium decor and they look lovely in a planted tank.

"Nice big pieces of slate."

Originally I set up a waterfall with them, but decided to fill the tank all the way. So I bought these thinking I'd get much bigger pieces. They are heavy and will slowly move if on a slope. Just be prepared to buy several bags if you have a 20+ gallon. I got these for a betta sorority tank. They get tossed around in shipping and chunks break off. I got a nice large piece that was about six or eight inches wide.

"So pretty."

After playing with them for awhile now. Waiting in my second bag as I'm typing this. I'll order this again, but for now I have more than I need! It's simple slate rock but it's natural and really great for my box turtle terrarium. I got a nice large piece that was about six or eight inches wide. The shapes very interesting and pleasant to look at. Photo 5 is a sample layout for my 45cm tank.

"No issues so far though."

It's simple slate rock but it's natural and really great for my box turtle terrarium. Was a LOT to clear off the gray dust if using in an aquarium. I'll order this again, but for now I have more than I need! These are excellent stones and a great buy for the money! You definitely get a lot of slate for the price. These glow very brightly and are super light weight. When I keep it lit for at least an hour, it stays glowing for at least three hours.

"You will not be sorry."

For the price, this should be solid resin. So glad I bought these for my tank. I couldn't find these at any of the aquarium stores near me, chain or independent. For an Iwagumi layout, this would be the Oyaishi. I switched up my plans a bit and everything was lovely. My only problem is trying to arrange them. It took about a hour to clean the rocks off.

"It's not a huge piece."

I got this for my 10 gal and it fits beautifully! Got this for my betta fish, he LOVES it. The edges of holes are also sharp, but easy enough to smooth with a razor knife. They are making these by sloshing resin around in a mold, so it's really thin. Honestly it's a good idea to have some glue on hand anyways. The largest of the remaining pieces was moderate sized and makes for a good Soeishi. Was a LOT to clear off the gray dust if using in an aquarium.

"Real look."

Perfect size just what I needed not as many as I expected. I switched up my plans a bit and everything was lovely. I am only giving 4 star because I had no way to request a larger stone after order. The result is a beautiful black rock with white lines. Provides an interesting texture to your aquascape. I wanted a large stone to stand out from the rest. And placed in a 36 gallon bowfront.

"What a deal!"

Just hit the add to cart and wait until you get the dust off and see them wet. Recieved 8 pieces of stone in my order with minimal chipping. Great stones, came with 3 various sizes for the 5 lbs option. Perfect size just what I needed not as many as I expected. It's a good price for what you get. I may have even used too much rock but I love how the scape came out with this rock. And I had some left over rock, mostly because I use a lot of driftwood and plants.

"LOVE these rocks!"

They arrived in tact and were all the size described. These glow very brightly and are super light weight. Great product and it will definitely be buying more. I got a nice large piece that was about six or eight inches wide. I love the stones, but yes, barely enough to cover a corner of my aquarium. Super happy with what, only downside is I should've bought 2. I had to break up some of the larger ones to fit what I was looking for.

"I ordered 2 sets."

My buddy said he found a better deal on etsy. Waiting in my second bag as I'm typing this. Will most likely buy more in the future. Just be prepared to buy several bags if you have a 20+ gallon. No I dont work for them and no I dont get anything for saying that. Absolutely perfect for use in my 20 gallon aquarium. It was well worth time and effort to get them clean.

"This rock is beautiful!"

I thought the price was great for the quantity and quality as well. Also, if you need any manzanita or any other driftwood. Overall, a great natural-looking stone in an aquarium. Stones were perfect for my 5 gallon planted tank. I also placed one or two inside her bathing dish to help her climb in and out better. And placed in a 36 gallon bowfront. I got 9 rocks in several sizes as noted in the pictures and several tiny chips.

Fityle Final Thoughts

"No complaints!"

The holed rock formation is a nice design, but the material being is way too thin. Originally I set up a waterfall with them, but decided to fill the tank all the way. But then again, it's 17lbs of rock so I struggled rating this one. I got six, nice sized chunks of slate. I wanted real stone instead of the fake stuff at the local box stores. Just trying to help you find good products for a good price. Provides an interesting texture to your aquascape.

I wanted a large stone to stand out from the rest. I'll order this again, but for now I have more than I need! And I had some left over rock, mostly because I use a lot of driftwood and plants. Also, if you need any manzanita or any other driftwood. Shipping was very fast and the stones were in excellent condition.

"I love theses."

He hides in it all the time and so far he hadn't torn any fins. When I opened the box I was so surprised and shocked. My cichlid love hiding under the caves. The price for the quantity of rock kind of drives me nuts. They are heavy and will slowly move if on a slope. The best part about this product was that it came with additional plants. The holed rock formation is a nice design, but the material being is way too thin.

"I got around 11 rocks."

I thought the price was great for the quantity and quality as well. The result is a beautiful black rock with white lines. Trying shipping this much heavy stone. You should never buy rocks but there's no Dragon stone down by the river. I used these for Aquarium decor and they look lovely in a planted tank. I was very pleasantly surprised with these dragon stones. Worth every penny, my nano looks great.
