Hi guest Smile

according to Barlow (1976)

the normal colour of A. citrinellus is grey with red or orange parts on its breast, fins, eyes and tail. Other "normal" A. citrinellus have a stripe pattern.
I guess they look like this one out of the midas gallery.



This stripe pattern can be strong (aggressive) or pale (relax). In the Apoyo lake - breeding Citrinellus are black.




You can find a lot of red or orange Citrinellus in their natural habitat.
This red, orange, white colour is a mix of pigment Betta carotene and Canthaxanthin without Melanin. Melanin covers the red or orange colour by normal A. Citrinellus







All A. Citrinellus born with normal colour
