Short-Lived Fish:
* Guppies: 2-5 years
* Goldfish: 10-20 years (some varieties may live longer)
* Betta fish: 2-5 years
* Neon Tetras: 2-5 years
Medium-Lived Fish:
* Angelfish: 10-15 years

Factors Influencing Lifespan:
* Species: The most obvious factor.
* Environment: Water quality, temperature, food availability, and predators all play a role.
* Genetics: Some fish are simply predisposed to longer lives.
* Care: Proper care, including a healthy diet, regular water changes, and a suitable environment, can significantly extend a fish's lifespan.
It's important to note that these are just general guidelines. There's no one-size-fits-all answer to how long a fish will live.
