    This is a variation of an idiom that goes something like “if you judge a fish by its ability to climb a tree, it will think it’s stupid”.

    But as someone who used to raise killifish, I actually found out that there is at least one species of fish that can climb trees.

      There is an aquarium supply store near me that has an open-top mudskipper display with a tree in it. Those guys definitely can climb trees.
