Metynnis fasciatus is a very rarely offered silver dollar which has a characteristic zebra pattern. Males and females can be easily distinguished in all Metynnis by the shape of the anal fin, which is straight bordered in females and has a lappet-like extension in males.
Now we could observe for the first time ever the breeding coloration of the males in one of our tanks. And this was really worth to have a look at! For the fish look fantastic with their pitch-black face mask. We were also able to make a small movie of that, you can watch the video on our facebook page.
