"Mysterious fruit tabs" sounds suspicious

There is an actual fruit that does this the tablets are derived from it.

No different than what goes on in any puddle or pond around the world.
Circle of life and all that, you know.

It's actually a fair bit different from a puddle or pond, given they are so totally enclosed; it gets a fair bit grimmer than a normal small body of water.

True that. Ammonia buildup inside the orb has nowhere to go (you can't change the water, and the branch doesn't filter), so after a few weeks the shrimp are basically breathing in their own waste. Now imagine the same tank after a few years.
Would you live in a room full of secondhand smoke?
