Our aquarium had 2 snails in it named Turbo and Guppo. They both died in the first three weeks of captivity. Then we added a fish named Ollie. We have elodea, duck weed, gravel and water in our aquarium as well. Our elodea has grown 2 inches since we got it. 

Our terrarium has a rock, twig, leaf litter, cricket, worms and grass.

The lowest piece of grass is 2 centimeters and the biggest piece is 18 centimeters. A week later, our worms and fish died. Now all we have for animals is a cricket.

The grass realize on the water to grow.And without  crickets the grass would get to high. and the worms used to help the dirt produce the grass.
