Bigeye

Bigeyes are nocturnal and feed on invertebrates and plankton. They have very good night vision, thanks to a reflective layer in the eyes similar to cats (tapetum lucidum). At daytime are they often staying in caves or underneath corals. 

Bigeyes are normally red, but can change color to partly or fully silver. Bigeyes are also called Bullseye and Glasseye. 

They can be 35 cm in length.
