Underwater Lego

Hi Lfan,

Thanks for your blog.  Now I have the perfect place to ask this question!

Lately I’ve had a desire to build an underwater model for a freshwater fish tank.  My major concern with doing this is whether or not submerging the Lego plastic in the tank would harm the fish somehow.  I’m not worried about the Lego as it can be cleaned, but I don’t know whether or not the plastic being submerged for a long period of time would be toxic to the fish.  Thanks in advance!

Dear Bryan,

I found this statement from the Vancouver Lego Club:

“After consultation with The Lego Company, it is indeed safe for all concerned. LEGO® is comprised of a very stable inert hard plastic and will therefore not breakdown in an aquarium environment.”

Since LEGO bricks are designed to be safe for children, your fish should also be fine.

Sincerely,

LFan
