Now this is an existential question.

Clearly for a sentient, social animal, this existence would be intolerable. (I am using a very broad definition of "sentient".) But does the shrimp have those qualities? Does the shrimp need or desire stimulation? Presumably, the shrimp would reproduce if the opportunity presented itself, but does it perceive the lack of that opportunity?

In ghost shrimp I've observed what looks like a rudimentary concept of "mine". They will grab an algae wafer and take it away with them -- trying to keep sole possession of it.

cf. Spexishness - a behaviour which seems to indicate intelligence, but is really pre-programmed instinct.

Can you link directly to the video? I'm not sure which one I should be looking at in the folder you linked to.

I once did the same thing with a similar palm sized glass orb for my office. I used ada aquasoil, hc cuba, some Staurogyne Repens, xmas moss and rotala indica. Actual water volume was probably a little under 2 cups. I used a 1 watt desk lamp led for lighting. Dosing only a drop or two of excel everyday. Weekly water changes. It was highly successful and ran for about a year with nice growth. I also added 4 cherry shrimp with grew to a 20 shrimp population inside of a little orb. I'll try and find a pic.
