self sustaining ecosystems have always interested me and I thought that its just a simple ecosystem so i am making this instructable I hope you like it.
I decided to add a bottle garden (one plant in a bottle or any airtight container) to a self sustaining ecosystem to add to the look
WARNING: this project contains live animals and no animals were harmed in the making of this nor should they ever be.
Step 1: Part One:
be sure to get some distilled water or you can get something that makes tap water ok for fish (the yellow bottle on the right.)
aquarium gravel or sand is good too.
Go to hobby lobby or any store that might sell vases and get a small jar or whatever that will fit into the second jar, the second jar must be very large or atleast large enough to fit the small jar in it and have enough room for fish and plants you can also get the glue gun and glass glue from there.
What is going to happen is you are going to put the smaller vase/jar into the bigger container.
you can also have decorations but i prefer the natural look.
(NOTE:be sure to wash everything very thoroughly)
