Since Bukang is definitely a fish, his intelligence is lacking, right?

If it were an orca or a dolphin, they would have swum toward that net at top speed and jumped over it, right?
But since he's a fish, he's just headbutting it;;
If an orca showed off a "killer whale show" by jumping once, humans might bring out a fishing net that's impossible to jump over altogether
But look at Bukang, even though it's not even that kind of situation, he's just headbutting it
This makes me feel like being a fish just doesn't work
He's nothing more than ingredients for shark fin
