i put lego in my 5.5 gallon with a few guppies. theres a car crash and a bar type thing and the fish are always swimming up to the lego ppls faces!

I'd still be worried about the sharp edge thing. Lego is, mostly, square as a rule. It's only through some weird out of the box thinking that you can make things nonsquare. if you did that there would be a strength issue to worry about.

I've been playing around with sculpey clay, which you bake in the oven and ends up plastic. You need a coat of marine grade resin over it, but it should stay waterproof after its dry. I think that's a better option.

not trying to be a downer, but I'm not sure it would work.

If someone has done it....I want to see pictures since that would give me something to do with my old legos. LOL

That is soooo cool!

IT's square but it's not sharp or anything. Kids play with legos. If you really want safe, go Duplo!

I want some room left i my tank! You could use some of the duplo blocks as caves on their own!

armadillo

Do you reckon? I didn't think it was so big? (long time since I last played Duplo, but you'd be more aware, as you got kids). Unless... You secretly enjoy building fortresses and cities with Duplo. Knowing your DIY bug, I wouldnt be surprised!

Junior duplo is huge, though don't know why, it's for little fingers!

heres something nice and time consuming for all the ppl worried about pockets of air and stagnant water between the lego's a 3/32nd's drill bit to make a hole in the top of every lego piece you put together i tend to be a perfectionist, "they say it's a Leo thing," and thats the way i would go i thought of filling each piece will silicone during assembly and that would be messy and time consuming i want to try the building it upside-down but i still would have stagnant water which i think would eventually build gases and break the whole project apart then i thought of a clear coat to water proof it after it was built but there are too many "ifs" there would solve the stagnation problem but not the bouyancy issue so making it actually able to have water circulation is the only way i know and remember if you consider this that there has to be an "in and out" for every block so maybe just one 3/16th's inch hole on the non-visible side of each block then standing it on the front would let all the air escape and provide a nice place for fry to hide inside of each block there are so many possibilities here everyone needs to keep at it we could see if lego could make things for aquariums anybody want to make that call? i would buy a kit from the store to build an underwater atlantis off subject again lol anyway just what i have been thinking since i first read this post Lee

clear coat won't work. I put that on a model once, and left it outside over night. It rained on it...the clear coat chipped as it dried. I wouldn't want chips in the water.

Besides clear coat isn't necessary. I do see what you are saying about the bouyancy, stagnant water though. And that's a bit worrisome. A bunch of drilling would solve that.

Of course, you would have less drill with duplo, and...depending on your aquarium...it just might work.

I still think I'll stick to PVC and clay pots though. I'm not sure how my girlfriend would feel about lego in the tank. LMAO

Instead of worrying about it rising ,have the bricks right side up as a floating cave. Fish could hide in a floating log just as well as a cave.

VertigoXLR8R222

wow! i had not given any thought to a floating structure! my problem is with my crayfish, Dud-a-Chum. he climbs on everything so i can't build a big structure or he climbs out and i have to go on a major search to find him so something floating mite be great have to try it out something round and balance that will turn like a log if he tries to climb on it and it mite help disperse the current from my filter could make a trench for it to flow into and out of for the fish to swim in some of them like the current lots of possibilities there i think i said that already i like this idea Lee

armadillo

I like the idea of a floating cave, but there is a slight risk of fish injury, isn't there? If the moving cave traps the fish between the cave and the glass for example.

im not worryed about still water or fish hurting them selves they run in to the glass and each othe enought so i think they will be fine with legos. to much worrying about them getting hurt will stress us all out to much and its not worth right?

Amnagrla

lol I thought the SAME thing!

COBettaCouple

i'm sure!

Beeboy

I researched the lego thing and this was what I got.

7) Is LEGO? safe in an aquarium for both the fish inhabitants and LEGO??

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.


So it is safe and opens hundreds of possibilities.

would lego be ok for my guppy fry because i feel bad about not letting them have a spot to hide!

armadillo

I think it might be easier to have a really densely bushed part of your tank. You could even use fake plants for that, that's easier.
