Technically maybe, but this seemed more like an animal-centric topic. Yes, technically, fluid dynamics are the same. But animals overall have a density much closer to water than air, so in this case the principles of remaining “aloft” are heavily influenced by that difference in medium. LTAVs more float than fly, and jellyfish more float than swim . When we say an animal flies, we are referring to heavier-than-air organisms using lift, not floating.
The general principle of generating lift is very different from the general principle of floating and propelling oneself through a similarly dense medium. I’ll concede bivalves as “flying” in water, since they do sink when not actively propelling themselves. But fish, the subject here, do not interact with their fluid the same way birds fly.

So guess it all depends on how you define flight haha. I don’t really see any reason tk argue over a silly comment on a silly meme.
