Very happy with this decoration
I absolutely love this little pagoda! It looks so beautiful and gives my aquarium a cozy, peaceful atmosphere.The first one arrived with a broken roof â probably got damaged during shipping â but Amazon quickly sent me a replacement. I returned the damaged one, and the new one arrived the next day in perfect condition!The quality is great, and the details are amazing. It looks stunning underwater, especially with the lights and plants around it.Highly recommend it to anyone who wants to add an elegant Asian touch to their tank!

Nice.
The tree pavilion is very beautiful, with realistic shapes and some small items. It can be said to be very beautiful. It’s priced perfectly too! I also like it. It brings a different scenery to the fish tank!Unfortunately, a small corner was cracked when it arrived at my home. The packaging was intact, including the inner layer tightly wrapped in a foam bag, but a corner still fell off. I used glue to solidify it.

Also doubles as TTRPG terrain
This aquarium decoration set also has a fun alternative use as attractive and relatively inexpensive terrain for tabletop role-playing games such as Dungeons & Dragons, where a set like this specifically marketed as a TTRPG accessory would usually go for 50-100% more than the asking price here.Conveniently, the smaller plants all come with bases that perfectly fit into a the 1″x1″ squares on common battle maps. The pagoda-like structure makes for great thematic set dressing.Everything is made of solid plastic (except for the centerpiece, which appears to be painted resin) and everything is put together well enough that constantly moving them from a box to the table and back over a few D&D sessions hasn’t caused any noticeable wear and tear.

Underwater Castle
This castle set transformed my aquarium into something storybook-worthy. The pieces are solid, with enough weight to stay in place once set in the gravel. Each part has details, arches, towers, and little openings that the fish enjoy weaving through. It feels like giving them a playground.What I liked most is that the resin is smooth and didnât have sharp edges, so I donât worry about fins getting torn. The eco-friendly design also means no odd smells or film in the water.

My fish love it.
This little castle is full of detail, and I like how the colors are bright and cheery – it makes my tank colorful and adds a splash of life. My fish swim around and explore all the little nooks. They look happy. This little castle adds personality to the aquarium.Construction wise… the material feels solid, lightweight, and cleaning is really easy – just a quick rinse and theyâre ready to go. I also like that itâs eco-friendly, so I donât worry about harming my fish or the tank environment.
