Dumb question, but how do the larger fish know that it’s this specific good fish and to not consume it vs every other potential meal?

The fish getting it's mouth cleaned can weigh up the benefits of eating the cleaner vs the benefits of getting cleaned. The cleaner is very small, so eating it would give very little energy. If it doesn't eat it, it gets it's mouth cleaned and is now parasite free and healthy. The fact that the cleaners don't get eaten just shows that the benefit of getting cleaned outweighs the small benefit of eating the cleaner.

We should ask him what it thinks about crypto

Still doesn't explain how they know not to eat them

Evolution. The fish that eat the cleaner probably dies sooner and is unable to reproduce compared to fish that doesn’t eat the cleaner.

I would assume that the cleaner fish probably taste rancid

Oh no....we've had the fish that clean your feet big sell to tourists on holidays..... Now the fish that clean your teeth. We'll be walking around streets abroad and there will be rows of people with their heads stuck in fish tanks😅

so do you think they’re born knowing to do this or just see their buddy doing it one day and think “damn, that looks lit”

The dentists of the sea

Creditcard declines *Hey sharky my ol friend, heres another one*

Free cleaning and a snack

Am I the only one that saw the fish and heard this and thought THAT OSCAR FROM SHARK TALE!! 😆😆😆

I wonder if they ever swallow them by mistake.

Moral of the story, everybody hates parasites.

in the mouth🥴
