There's always fish in the sea

[Tyrn]

Hi,

Is there a Spanish analog?

[Rusty]

There are other fish in the sea.
There are plenty of fish in the sea.
(Sometimes you'll hear this idiom repeated with "there's" at the beginning, but it should be "there are.")

Hay otros peces en el mar.
Hay otros peces en el agua.

[ROBINDESBOIS]

Hay mucho pez en el mar though is not widely used, we use different expressions.
