"Thank you to the seller."

Overall, a great natural-looking stone in an aquarium. If you are thinking about buying these, DO IT. I may have even used too much rock but I love how the scape came out with this rock. The rocks were REALLY dusty, covers with a lot of clay. Not bad at all for twenty bucks total. Dragon stone has a nice reddish tone to it so it really stands out. I got six, nice sized chunks of slate.

Marina A987 Final Thoughts

"Im very happy."

The edges of holes are also sharp, but easy enough to smooth with a razor knife. Not sure why but I just expected more. The water deactivates it and makes it safe. I switched up my plans a bit and everything was lovely. You should never buy rocks but there's no Dragon stone down by the river. Provides an interesting texture to your aquascape. I had to break up some of the larger ones to fit what I was looking for.

"Real look."

These are just what I needed to creat stone walks in my model railroad park. Also, if you need any manzanita or any other driftwood. So glad I bought these for my tank. Absolutely perfect for use in my 20 gallon aquarium. Love this product did not change colors when water ran over it. I got a nice large piece that was about six or eight inches wide.

"Exactly as described."

I wanted a dark rock decoration for my 5 gallon. The bag I received was 17lbs and the rocks were in good condition. They are the perfect little hideaways for them! Truly something unique that will appeal to any aquarist. These glow very brightly and are super light weight. Trying shipping this much heavy stone. Cleaned the dust and clay residue off under running water and some brushing.

"Very pleased with it."

Recieved 8 pieces of stone in my order with minimal chipping. They fit perfectly in my ten gallon aquarium. The resin color is dark, so no repainting needed. I soaked the rocks for about 20-25 min, took them out and hosed them off really well. After playing with them for awhile now. My cichlid love hiding under the caves. I purchased these for decor for my aquarium and I adore how they turned out.

Aqua Della 234-104569 First Impressions

"These are kinda gorgeous!"

Dragon stone has a nice reddish tone to it so it really stands out. It's not difficult but you need rinse over and over to get the water clear. Great seller, great product, great price! The result is a beautiful black rock with white lines. It's simple slate rock but it's natural and really great for my box turtle terrarium. Super happy with what, only downside is I should've bought 2. Every living thing in both tanks are healthy and as far as I can tell happy.

Aqua Della 234-104569 Final Thoughts

"Accurate description."

For the price, this should be solid resin. I'm always hesitant to buy it online, but this was a good transaction. The holed rock formation is a nice design, but the material being is way too thin. So I bought these thinking I'd get much bigger pieces. The resin color is dark, so no repainting needed. Don't even hesitate purchasing these stones. They get tossed around in shipping and chunks break off.

"I will be buying more."

They fit perfectly in my ten gallon aquarium. Different shapes and sizes to work with. Love these rocks and you usually get 1 big, 3 Med and the rest small. Hope this helps anyone that was wondering how we got our rocks so dark. For an Iwagumi layout, this would be the Oyaishi. Com is the only place I trust for my tanks. It's not difficult but you need rinse over and over to get the water clear.

"It wasn't horrible."

I will not be able to get all 7 rocks in my Bio Orb 8 gallon tank. I couldn't find these at any of the aquarium stores near me, chain or independent. Not sure why but I just expected more. The colors of the rocks are beautiful. I wanted a dark rock decoration for my 5 gallon. It was plenty for the tank I wanted to scape. Great seller, great product, great price!

Not sure why but I just expected more. Waiting in my second bag as I'm typing this. It was well worth time and effort to get them clean. The rocks were REALLY dusty, covers with a lot of clay. These are just what I needed to creat stone walks in my model railroad park. I hate negative reviews for awesome items just because the buyer didn't read! Great seller, great product, great price!

"Thank you!"

He hides in it all the time and so far he hadn't torn any fins. Shipping was very fast and the stones were in excellent condition. These broken bits are perfect for little details and filling gaps. They are making these by sloshing resin around in a mold, so it's really thin. You should never buy rocks but there's no Dragon stone down by the river. I am looking forward to getting my tank stocked up! Also, if you need any manzanita or any other driftwood.

Universal Rocks AQUARIUM DECOROCK-052-A Final Thoughts

"Perfect for her fishtank."

My cichlid love hiding under the caves. And I had some left over rock, mostly because I use a lot of driftwood and plants. The holed rock formation is a nice design, but the material being is way too thin. The structure is roughly 14l x 6h x 4d. Other fish may not like the ph change. Honestly it's a good idea to have some glue on hand anyways. The only thing that was frustrating was the wait time for the shipping.
