the last blog 11/12

This week my microaquarium got a fill-up, to counteract the water loss that had been occuring the last two weeks.

I found 3 aeolosoma, worm-like creatures, in the sediment that were much larger than when i last saw them.  1 aeolosoma was also moving around near 2 plant B traps.

2 dark ostracods were in the sediment, and 1 was near the very top of the aquarium, seemingly trapped at the surface of the water above plant B.  Also, this week there were two new ostracods, one of which was very young and tiny and the other was slightly larger, but neither had acquired their dark color yet.

Two of plant B's traps are still blue-purple, possibly signifying that they are dying, most are transparent, and a few have dark spots in them or are murky.

I sighted 4 cypria: 1 in the sediment, 1 near one of the blue traps of plant B, another eating a long strand of plant B, and another swimming around plant B.

I sighted a couple very tiny nematodes moving around in/near the glue around the sides of the aquarium.

Finally, I sighted 1 cyclops copepod near the top of the aquarium, moving infrequently.

More O2 was produced this week, as evidenced by the larger bubbles.  Also, the water level seems to have gone down significantly this week, possibly due to some evaporation.

I spotted a cyclops copepod swimming around near the bottom.  There are 3 dark ostracods left: 2 in the sediment on the bottom, and 1 on plant B.  I also spotted 2 cypria on plant B, and 1 on plant A.

The traps on plant B appear empty for the most part, but they also appear to have grown longer tenticles since last week.  Some of the traps are transparent and some are dark, but one is blue for some reason.

Both plants A and B produced some oxygen since last week, existing in the form of bubbles.  Plant A had 2 nematodes eating it, and several others interspersed throughout the open water around it.  Plant B was being eaten by a cypria, a kind of ostracod, and another was eating plant A.  I spotted an immobile cyclops copepod, but there was at least one other swimming around plant A.  There are 3 dark, unidentified ostracods left, that i can see.  3 are in the sediment at the bottom, 1 is immobile, and 1 is swimming around and eating plant A.  All the traps on plant B appear empty.
