Fish of this family eat mostly insects and other invertebrates.
==Reproduction== Fish in the subfamily Oxyzygonectinae are ovoviviparous. The Anablepinae are livebearers. They mate on one side only, right-"handed" males with left-"handed" females and vice versa. The male has specialized anal rays which are greatly elongated and fused into a tube called a gonopodium associated with the sperm duct which he uses as an intromittent organ to deliver sperm to the female.
