    • Legos are always 5 stars!
This fishtank is cute as can be! The colors are awesome. It was pretty simple to put together. Perfect for a kid, teen, or kid at heart! This set makes a great gift. No fish food required!

I love this Lego set and came as described. We also ordered the light to go with it, so it can light up

    • Much smaller than it seems
My husband bought this for our daughter and he also purchased the light kit that goes with it. It ended up being a lot smaller than he expected and our daughter does not like the optional lights he purchased. If someone bumps into the frame of the fish tank, it easily moves or breaks. It looks good though and was not too difficult to assemble. ... show more

I never have to worry about the quality of Legos. I bought this one, along with the dolphin and lights, for my grandson's birthday. He was intrigued by the lights as none of his other sets have them. He will be putting the set together on Christmas break and I'm excited to see how it turns out!
