Description
The Smallscale Hardyhead, Atherinomorus lacunosus, is a slender, silvery fish characterized by its schooling behavior and adaptability to varying salinities. Found in coastal and estuarine waters across the Indo-Pacific, it primarily feeds on zooplankton and small invertebrates. While not a common ornamental fish, its hardiness makes it an interesting, albeit challenging, species for dedicated brackish or marine setups.
