Datnia plumbea Kner, 1864 Leiopotherapon plumbeus, known commonly as the silver perch,[1] is a species of ray-finned fish in the family Terapontidae, the grunters.

It is endemic to the Philippines, where it is called ayungin, bugaong, bigaong, and bagaong.

[2] The species exhibits paternal care, as the male guards and tends the eggs.

The supply has run thin due to overharvesting, and it is now rare in markets, making it quite expensive.

[4] The fish is being reared in captive breeding projects, in which it grows well on a diet of prawn food and tubifex worms.
