Bicolored Coney, Cephalopholis fulva

Good morning friends, I have a super colorful little sea bass for you all today called a Bicolored Coney, or Cephalopholis fulva for you masters of fish out there. The coney (Cephalopholis fulva) is a relatively small grouper species which occurs in three main color forms: a red or dark brown form, commonly found in deep water; an orange-brown or bicolored form, orangey-brown above and pale below, which usually occurs in shallow water; and a yellow (‘xanthic’) form, found in both deep and shallow water. In the first two forms, the head and body are covered in small, dark-edged blue spots, while in the yellow form the spots are fewer and are confined to the front part of the head and body. In all color forms, there are two prominent black spots on the tip of the lower jaw, and also two prominent black spots near the tail. Like many groupers, the coney is able to change color, and at night may take on a pale coloration, with irregular vertical bars and blotches. Individuals can also apparently change between the all-red or all-brown form and the bicolored form, whereas yellow individuals do not appear to change. The coney may change to the bicolored pattern in response to excitement, or the pattern may aid in concealing the fish at certain times of day.

Thanks to for that wonderful hard to find info!
