Explanation:
Sparta was jealous because Athens was acquiring wealth and it did not set well with Sparta.

The Peloponnesian War started when a long series of conflicts between Athens and Sparta that lasted from 431 to 404 BCE, took the shape of war.
The primary reasons of the war were that Sparta feared the growing power and influence of the Athenian Empire. The Peloponnesian War began after the Persian Wars ended in 449 BC. The two powers struggled to agree on their respective spheres of influence for absent Persia.
This disagreement between the two led to friction and eventually took the face of war.
