>Nigerian Green Wow these are appearing everywhere. Mine were sold to me as "Yellow kribs". They are P. taeniatus and the green is just appearing under the chin on my males. Males Females No spot in dorsal Obvious black spot in back end of dorsal Pointed, elongated ventrals Rounded , shorter ventrals Dorsal trim goes to tip Dorsal trim ends before tip Mine have orange eyebrows and orange in the dorsal, others report red eyebrows. BTW, they are difficult to sex (for me) until they are at least 2 cm. By then the males are also usually the larger fish in a mix. - -Doug
