What type of fish last longer?

It's impossible to say definitively which type of fish "lasts longer" without more context. "Last longer" could refer to:

* Lifespan: Some fish species live for decades, like the Greenland shark (estimated 400 years) or the Koi (over 200 years). Others, like guppies, have much shorter lifespans of only a few years.

* Freshness after caught: This depends on how the fish is handled and stored. Generally, fatty fish like tuna and salmon spoil faster than leaner fish like cod and tilapia.

* Durability in an aquarium: Some fish are hardier and more adaptable to different tank conditions than others.
