Couple of festivum ?'s

[Rupununi]

The only real difference I ever noticed in mine was size. Males always ended up twice as big as females. Most of my males were pushing 8" after a year, while females started spawning around 3 - 4". They only grew to maybe 6". The males would also be much stockier with a thicker forehead.

Here is a video of a young pair. These fish were less than a year old. As you can see, the only real difference is that the female is smaller. In both groups I kept (which were wild-caught) the females were always smaller than the male.77.photobucket.com/albums/j49/ryansmith83/b4a06524.jpg[/img]

And a large male:

ryansmith,

Thanks, you've been very helpful.

I took some photos yesterday. I may have it backwards. I could have sworn the female was the attacker but from these pics it looks like the attacker has a larger forehead than the victim. The victim fish has a thicker head, when viewed from above, but the forehead is not quite as prominent as the other. Please take a look and let me know what you think:

Victim: Notice the short pectoral fins (missing streamers) and tattered dorsal/caudal fins:
