LEGO in Fish Tanks?

MattPetersenMattPetersen Florida, USAMember Posts: 282
I am setting up a fish tank in my classroom and I was thinking of incorporating some LEGO minifigures or blocks into it via bottom of the tank decor.
Has anyone done this before?
is it safe for the fish (my primary concern).?

    I did it before. Sunk a pirate ship for a few years in my brother's tank. I don't think it shortened the fish's lifespan any. Now, I did have to seriously clean those pieces when they came out. That was the worst of it.

    The only risk is if the fish eat the smaller parts. But I doubt they separate those same small parts. And even then most fish are smart enough to spit out non food objects.

    Your biggest problem will be getting it to not float. Lego construction methods trap a lot of air.

    Submerge all the parts first and build underwater!

    Alternatively fix a plate to the tank floor, or weigh one down, and attach to that.

    I assume you'll be using set #21306 The Beatles Yellow Submarine?

    Depending on how long you leave them in there and the lighting, they could discolor. The aquarium in my city has three small tanks with LEGO sets in them. They've been there a while at this point and the colors look off.

    Was thinking of placing a few Deep Sea Diver minifigures from the minifiure sets, on the bottom with some LEGO sharks, Octopus and Aquaman. 

    The Yellow Submarine would be sweet! But I think most elementary school kids wouldn't care and I'd rather keep that set in a nice display. 

    Anchoring a lego plate at the bottom was my thought as well.

    If you want to make them look suspended above the bottom, use a trans clear bar 99784. They are almost invisible in water.
