I want to make a habitat out of 3l and 5l boiling flasks

Kind of a rough idea to start. I think I'd like to do more chambers. i can get them with anything from 1-4 necks, making it pretty easy to expand and do a more 3d shape. 

That looks really cool. You should make it.

Oh cool! I like the idea. Have you ever heard of Aquaponics, Spleen? Might be something worth looking into.

I will once I get a final design down. And money. >.>

I have, and I'd like to use something like that in this setup. Ideally I'd have some insects, something that lives in water, either super small fish or shrimp, and something that would be happy in the small space of land. Frogs or lizards, most likely. Do the full circle of life thing. 

If you've got amphibians and fish your best bet would be to fill them with something like fruit flies because they breed so quickly your apex predators wouldn't run out of food.

Yeah, that's what I was thinking. Or like mealworms maybe.
