Arowanas are large fish, so it is no surprise they lay large (and dramatically golden) eggs.  Arowanas are also paternal mouthbrooders, meaning the father incubates eggs in his mouth.

This Korean video captures Golden Asian Arowana courting, copulating, laying eggs, and taking up the eggs into the father’s mouth … all within two minutes.  Not only is the behavior fascinating, but it’s always great to see captive breeding of endangered species.
