Unique in the fact that males and females display colors. Males display a more powdered blue color whereas females are a more drab blue, but lack egg spots on the anal fin.

Sizing and difference between Adults and Juveniles.

When we list size, it is the minimum size that is currently being offered. It can and, in many cases, be a little bigger than what is listed. All measurements are from the tip of the snout to the tip of the tail fin. Many of our fish look far different as juveniles than they do as adults. Also, in most cases, males are much more colorful than females. We do our best to provide pictures of both an adult male in breeding color and a picture of juveniles. We are asked occasionally how we can sex fish at the juvenile size. Sexing fish at juvenile sizes is easy if you have the experience and know what to look for. The real trick is to make sure you have 20-30 of the same fish in the tank. Then you can usually pick out several that are showing dominance in the tank. When in doubt, we do vent them with a high-end, video magnifier.

As always, if we make a mistake and you have bought a listing for a guaranteed male and it turns out to be a female, then we will replace it at our cost no matter how long it has been.


We guarantee live arrival and good health on all fish we ship. We lose less than one percent of the fish we ship but problems do occasionally occur. If you have a problem, please photograph everything you think is relevant and notify us by e-mail immediately. It is our choice whether to replace or refund any live fish we have shipped to you. (In most cases, we replace any problem fish) We will fix any reasonable problem to everyone’s satisfaction.
