Is the goby fish smallest fish?

No, the goby fish is not the smallest fish. While many goby species are very small, the title of smallest fish goes to the dwarf pygmy goby (Trimma caespitosum), which is only about 8 mm long.

However, there are other tiny fish, such as:

* Paedocypris progenetica: This fish from Indonesia is only about 7.9 mm long and is considered the smallest known vertebrate.

* Schindleria brevipinguis: This species from Australia is only about 8.4 mm long.

So, while the goby fish is known for its small size, there are other fish that are even smaller.
