Alternating layers of aquariums, and terrariums, a laminated paludarium.

Ingredients:

1- A standard aquarium, it would have to be pretty large. 2- Several panes of glass the same size as the front of the aquarium.

Insert the panes of glass into the aquarium to create several segmented, layered compartments. Think of a file cabinet.

Fill each compartment with gravel such that it slopes upwards from front to back. Carefully make sure the gravel fill looks like one cohesive bottom.

Fill some compartments with water, some with terrestrial plants and animals. Fish swimming with birds, gerbils playing with snakes, frogs and butterflies all happily living together in peace and harmony, the way God meant things to be. None of this nasty food chain business.
