A. panduro sold as a male - female pair (young immature still but sexable) at approximately 1.5" (4 cm).   Sex cannot be guaranteed due to the fact that some fish at this size do not color up fully and could be "hiding" what sex they actually are.  But from our experience, a male - female pair can be determined.
 
Also selling unsexed smaller juveniles at about  0.75" (2 cm) as a group of 6. (Recommended to ensure both males and females.)
 
Apistogramma panduro (Sometimes known as A. pandurini) is a popular Apisto from Peru. These fish are often called Panda Apistos/Cichlids, due to their dark mask on a light, bluish body. They also have reds and yellows in the tail fin, this being especially pronounced in males. 
 
These are young captive-bred individuals, approximately 1.5" long. They are just starting to colour up. 
 
Photos are typical of the fish being offered and are from our tanks.
