Any interactions between the sea gods?

Just finished the Theogony, and I appreciate that the Greeks are a seafaring, island-dwelling bunch, but there’s a lot of sea gods.

Pontus, Oceanus, Nereus / Old Man of the Sea, Poseidon and all the Oceanids and Nereids.

Are there any stories about interactions between them, or squabbles about who is actually in charge of this domain?

Poseidon sticks out as the only one assigned into this role by Zeus, whereas the others are descended from Pontus. Do the other sea gods resent this neptunian nepotism?
