Answer: If properly protected Lego is aquarium safe and can be used in aquariums with fish and other aquatic friends like shrimp and snails.
You see there is some confusion on this topic for example;
Over at aquariacentral one of their users seems to have contacted Lego and they confirmed that Lego is indeed safe…Lego is made of very stable hard plastic and will not breakdown in an aquarium.
However, if you actually look at Lego.com they have the following statement;
We don’t recommend you use your LEGO® bricks as decorations in aquariums or fish tanks. Additionally, there are also a few types of LEGO® parts that should never be put into water.
Which is an odd statement considering the hundreds of pictures and videos where people have placed Lego in an aquarium. In fact, the video below shows a Lego Aquarium located in Legoland Denmark.
Apparently, It contains 4 lego submarines, 15 lego divers and approx 230,000 lego block were used in the aquarium display.
