Observation 10

In the top part of our terrarium, since cutting the hole and leaving it for a week, most of the condensation that was in the bottle has left and the bottle only has a little bit is up in the corner opposite of the hole we cut. Our plant has not improved, one of it's leaves is brown and breaking down, another is getting increasingly brown and close to the point of breaking down as well. Our plant is leaning against the bottle and cannot stand up by itself. 

Are possible dead snail

The water is clear at the bottom and our elodia and algae is thriving and green, especially as always, the elodia which now occupies most of the bottom of the terrarium. Out fish is alive and healthy, swimming around in the forest of elodia. We fear our snail is dead, he is just balancing precariously on a leaf of the elodia plant. The ring of algae at the surface of the water has increased since the last observation.

Observation 9

In our top section the plant is still green and leaning over, the leaves are turning more brown at the center and edges and there is a lot of condensation present still. There are some white deposits of some kind in the dirt.

Our plant has browner leaves now

In the aquatic part of our terrarium the water is still very clear. Our guppy is alive and well, happily swimming (we observed it depositing waste). We discussed about what we believed the guppy was still eating because the fish food we put in the water 9 weeks ago is probably gone. We thought that the algae or the nutrients from the other plants could be keeping the guppy alive.  Our snail is also alive and moving around, still not as fast as before. Our elodia is becoming darker at the bottom but it continues to grow. Our algae which we had previously thought was dead has grown and is more green than before. There is a green lining around the top of the water's surface, like some sort of green algae that has grown around the bottle. 

There is some green residue around the top

Our terrarium weighs 1.549 kg

For this next week we are cutting a hole in the top of the bottle to see how that affects our closed system.
