I started out with 7 Juv 1-1.5" ornatums in a 55. Right away after transport they came down with ick and one didnt make it. Then shortly after one jumped out the back of the tank so I was let with 5. Those 5 lived in the 55 for a wile and as they grew and as time went on the pecking order started to fall into place. There was always one that seemed to be the dominant larger one of the tank and had his place under the slate. That one is the lager one in the vid that looks to be a male. He was always the in the background, not chasing the other 4 fish much and liked to stay under his slate. The one in the vid that I think might be female is the one that dominated the other 3 fish and never really messed with the larger presumed male. This one looked different in color too than the larger presumed male...either being the dom female or a sub male I dont know. As time went on that one presumed female killed one of the other 3. I tried to pull it out but it was too far gone and died. Then last night there was another victim of the presumed female but I was able to pull that one and altho badly beaten I think it might make it. As of now there is one left in the 55 that is hiding almost completely black in the upper corner and if the presumed female sees it she will give chase. Now the larger presumed male doesnt pay much attention to it. With the other fish out of the tank (or site) these 2 remaining seem to hang out decent...usually that presumed female is chasing the others all over but now it seems they kinda stick together with out trying to kill one another. In the vid you can see the color difference. The presumed female has blue spangles on the face but not a lot and the over all body color is a tan/yellow where as the presumed male is more blue and is heavy spangled in the face. I notice this difference in my adult ornatums I have too. So maybe they have started to bond? Or maybe its a dom sub male thing? Time will tell...what do you think?

. I have one question though. Is it Ornatus or Ornatum??
