Bigeyes (Priacanthidae) are nocturnal, carnivorous, mostly red, medium sized (up to 12” long) reef fishes comprising 4 genera and 18 species. Most species occur in relatively deep water and some species have commercial value as food fish. Bigeyes have not been cultured in captivity.
The glasseye (Heteropriacanthus cruentatus) was reared from a small number of eggs collected in waters off the west side of Oahu in May, 2012. The eggs are pelagic, spherical, measure about 0.75 mm in diameter and have an amber-colored oil globule.
Features of the larvae include large eyes; a large, broad head; a long, serrated preopercular spine, a well-developed supraoccipital serrated crest and spine; and yellow and brown pigmentation. The larvae are hardy and appear easy to raise, especially in the later stages (post-flexion). Unfortunately, later stage larvae also have tendency to overfeed (on artemia nauplii) and died before completing transformation. DNA barcoding helped identify the species.
