The guppy lifespan average is 3 years. Some live it out in 1.5 years, and others as long as 5 years with amazing care from owners.
If as a youngster tank water is kept warmer, they will grow faster, but will have a shorter lifespan in water temps warmer than 76F-ish. However in cooler waters (72-76F) they grow slower but tend to live longer.
Their lifespan is also based on their pH and water hardness they are kept in and how they were acclimated to it. Guppies prefer a higher pH and med-hard water.
How long have you had your guppy? Can you tell if there was any ammonia, nitrites, or anything else that could have killed him? Were any other fish acting different? Could it have been a parasite?
