Incentivised review
We loved the idea of a Lego fish tank so we looked forward to building this. In the box you get 3 designs you can build using the bricks, but you can only do one at a time. There is the fish tank, art easel and treasure chest. It is very easy to build, took us about 40 mins, there were some fiddly bits. All the fish are easily built and the plants too. My children absolutely love it, fish without having to worry can’t be a bad thing. It has brought lots of fun for them. The other builds are easy to make as well, but we love the fish tank the most. Overall, I love this set, it’s very cute and is a nice size. We really love it, would definitely recommend.Play Experience4.0Value for Money4.0Was this helpful?

Average rating4out of 5 stars4.0A beautiful experience
I would recommend this to a friend!
This entire kit is a joy to build, and I can't recommend it strongly enough. There are several design choices early in the instructions that are a little mysterious at first, but once it all comes together, it's just brilliant. The subject matter is beautiful, and the model itself serves for great inspiration for expansion of your aquatic display. Already, I've expanded with a second aquarium and two other models, adding more sea life. That there is so much room to grow and expand this makes it just as relaxing to build, grow, modify, and maintain as the Bonsai tree.Play Experience5.0Building Experience5.0Value for Money5.0Was this helpful?

Average rating5out of 5 stars5.0Finding nemo
I would recommend this to a friend!
This set reminds me so much of the film finding nemo that I added a few extra pieces to it like the sharks a stingray some divers flounder & Sebastian I tiled the bottom with the darker blue transparent tiles & also finished the sides with the transparent pieces I made a lid for it & put my spare printed Disney tile I had left from my Mickey Mouse art sets on the front instead of the plain black one it makes it look so much more like a fish tank now plus with the added benefits of keeping the inside dust free it’s a beautiful set & I would recommend especially if you love fish I used to keep fish for over 20 years but sadly had to give up due to my health so it’s nice to have a little tank to look at without the hassles of maintaining it not much more to say other than I would buy it why it’s still a available setBuilding Experience5.0Value for Money5.0Was this helpful?

So I wanted a fish tank without all the hassle… I’m a Lego fan, have been since childhood. Bought this … I smile every time I see it. It’s very small but I’ve added my own lights and use it as light too. Love itPlay Experience5.0Building Experience5.0Value for Money4.0Was this helpful?
