That's kind of weird. Insects are shown to be sentient but fish aren't.
Not that much weirder than the reverse to be honest. Lots and lots of insects are sentient, and so are most fish. There are tons of fish far closer to the status of what we call sapience than some mammals, but our culture also kind of arbitrarily labels them all as lower on the sapience totem pole because "they" just look and think so obviously different than us.
Now i'm curious. What kind of fish Are so close to sapience?
Off the top of my head I know entire families of fish that are socially intelligent enough to engage in deceit and individuals show preferences, subordination and social behavior in single and grouped fishes, which ticks basically all but the most ludicrous criteria set by any reasonable philosopher of mind.
