What can you tell me about the Spikefin fish?

Question

Where it lives, how deep, how rare, what it eats, can it live in a fish tank, life span, breeding habits, if I want to go diving and see one where should I go?

Answer 1

Right here:

Just kidding... See here:
http://en.wikipedia.org/wiki/Mabul

According to that wiki, you can find spikefin gobies near Malaysia, particularily around Mabul Island.

And according to this:

They eat microfauna, can live in a fish tank (they sell them!), and are apparently not terribly rare.

Hope this helps!
