Mini ecosystem

     This week my niece and nephew helped me make a mini ecosystem.  I did not have any 2 liter bottles so I used orange juice bottled instead.  We put glass stones in the bottom, a moss ball, a snail and 2 ghost shrimp.  I named the snail Gary “I know, how original” and the two shrimp Scampi and Coconut. 

Step one: add moss ball


Step 2: Add snail


Step 3: Add shrimp.  I do not have a picture of this.  They were a little tricky to add since one wanted to stick to the bag and not go in the water. 

Then in the top bottle we added soil and grass seeds.  Then opening to the top bottle is covered with a piece of cloth held with rubber bands. This prevents the soil from falling into the water below. 


Here’s Gary!


The area that they have to swim around in is too small so I might have to redo this using 2 liter bottles.  The shrimp like to follow Gary around.  Gary likes to hang out on the moss ball and sometimes will slid up the wall.  

Ghost shrimp eat plankton and flake food. Since this is a new “aquarium” I will give them some flake food so I know that they won’t starve.  The snail should be content with the moss ball and the left over fish flakes.
