FEDOUR Aquarium Mountain View Stone Ornament Tree Rock Cave Landscape, Large Aquarium Ornament Rock Artificial Fish Tank Decoration

It’s very large it almost protrude to the top of a 20 gallon tall tank and then take up about half the space if you put it on one end and the center it looks really nice. I love it and I will purchase again.

Good quality material. I thought my Betta was devouring my shrimps after I got this thing. Nope. They found a way to burrow a underneath and hide inside of it. Keeps them safe, they love it. At night they do come out and scale the mountain alongside my snails. Pretty neat to watch. And the betta and guppies swim through the little tunnel so fun for all.

No complaints about this decoration. Fish love the tunnels and its been great for fry hiding out. It does tip over easily if you are working on the tank so be mindful of that.

This is just one piece, even though it looks like two "mountains". Bought to create a "look" for my 20 gallon long aquarium. It's currently on the bottom of the tank, but I'm going to raise them up on an underwater platform so they emerge out of the water to look like certain monoliths that project out of the ocean off the coast of China.

Bought both sizes as the main attraction to my new 40gal tank

I ordered three items like this and all three arrived with some degree of breakage. I agree with some of the reviews that mentioned there were some sharp edges on the inside and bottom. I don't think that's going to be super problematic for my hermit crabs. I'm using these as a way for them to climb in and out of their water tanks. The item measures as it was supposed to and looks very much like the picture and I'm satisfied with that . This item is really just cast resin with paint and some little plant things glued to it. It looks pretty good but it certainly isn't hyper realistic. But it looks natural enough for a crabitat and it does lend itself to an overall natural feeling of a water environment. the box wasn't damaged and it looks like some kind of effort was made to pack it carefully but it's not as good a quality as another item I received that was a similar kind of cast resin rock formation. It's good enough for my purposes but overall it's just average.

I use my in the terrarium praying mantis and crickets love it

I bought both the large and the smaller rock caves for my 55 gallon tank and they look great! I even used the included fake plants while some of my real plants grow out. They arrived intact and VERY well packaged. It's obvious the seller listened to some of the poor packaging reviews and updated their process. No odor whatsoever.
