Yes, it's an interesting question to discuss - is it fair to keep him captive?
To many people, a fully-enclosed sphere seems less ok than an open-top tank. Interesting to ponder why that is...
a) He's not starving, clearly
b) No companionship for the last few years (c.f. The Martian)
c) No stimulus like wind, rain, current, belly rubs; no intellectual stimulus either
d) Range of motion: The sphere's diameter is about 15x the shrimps body length, so longer than many of the larger fish in home tanks or goldfish or bettas. (I'm not proposing that those are fair! I think to be really ok, we need tanks so big that natural range isn't limited at all, like 1000x bigger)
e) No predators or pathogens
f) No chance to procreate
Does this case have a different moral situation than keeping any creature captive under any circumstances? Discuss.
