Where is a sea dragon fish from?

You're likely thinking of a sea dragon, not a "sea dragon fish". Sea dragons are a type of fish, but they are not called "fish" in their name.

There are two types of sea dragons:

* Weedy sea dragons: These are found only in Australia, specifically along the southern and western coasts.

* Leafy sea dragons: These are also found only in Australia, but they are more common in the cooler waters of the south coast.
