Good morning!
Good morning to everyone in the Northern Hemisphere!
I am your most miserable, most undignified servant, the Tooth-Cavity Angel!
I saw it, or rather... it is completely beyond my comprehension, but Polnareff will describe what happened as accurately as possible.
I happened to witness my female guppy, named Elo Noir, biting into the head of a freshwater snail and swinging it around.
I couldn't tell if it was a healthy snail.
It might have been dying, or it might have just died.
Then, just like a human eating a turban shell, Elo Noir pulled out the snail's body.
Other guppies gathered around and it was a wild party.
She couldn't bite through the snail's body, so she swam around and swung it around, kind of like a crocodile.
They're the same size as killifish, just a little bigger, so how can they be such aggressive and ferocious fish?
Goldfish won't eat small snails unless they're quite large, and I've never seen even those ferocious silverfish attack a snail.
In fact, yesterday morning I had already witnessed them eating what appeared to be a clam.
I thought for sure they hadn't missed the exhausted clam and had gone for it, but is it possible that the clam, which is filter-feeding, had bitten into the straw-like thing and pried it open?
The second generation of guppies are already multiplying in the Biocube, and if they all start acting aggressively, I'm very worried about the survival of the other animals.
The Japanese freshwater shrimp could easily become extinct.
The amphipods might be in trouble too.
Even snails and mussels can be attacked by the guppies if they get serious.
So, if all of these creatures really do become extinct, will the guppies then become extinct as they have no food?
From what I've found, it doesn't seem to be the case.
It seems that even if there is no carnivorous food left, guppies can survive by gnawing on microorganisms and plants.
In their native habitat, guppies become omnivorous and lean towards herbivorous diets in places where there is no abundant food, and so they survive.
If that happens, food shortages will likely slow the population, but the 1-ton mini-Earth "Biocube" may have to survive on just aquatic plants, microorganisms, and guppies.
Even so, it looks like we will be able to achieve our original goal of "changing generations of fish."
But for some reason, I feel very sad about this happening.
In other words, my ideal food chain is like this.

If it turns out like this, it's only natural to feel sad.

Anyway, the experiment with the 1-ton mini-Earth "Biocube" has moved from the stage of "waiting for guppy fry" to the stage of "praying for the survival of shrimp, amphipods, and shellfish"!
