How is it that blacks, kept in exactly the same conditions, don't develop them? Isn't this an agrument for genetic predisposition?

I think genetics does have something to do with it, but I also beleive that there is a trigger to cause it. There have been claims as of the effects of keeping Silvers in ponds has on drop eye, but these claims lack substancual proof.
If the ponds do work, then I beleive the lack of trauma from head bashing is more probable then "it makes the aro look up" theory.
DE can be caused by silver Aro's jumping and pumping into the tank cover. I have a set of pictures post on WW, they show clearly that one of my silver aro was injured from hitting the tank cover, and his eye ball was bended downward.
I don't see any proof to backup genetic or food causes. But I have solid evidence to show that injury causes DE.

I also support the theory that DE is from injury when sliver Aros jump and bump into the cover.
I raised all my previous silver Aros in my 1000G. The tank's cover is 1 ft or more from the water level, so it is not easy to bump into. None of them got DE, the largest one grew to 20".
I now have 3 silvers, ranging from 14" to 17", they were kept in 1000G and didn't get DE. I moved then to the 180G a few months ago. There is only a few inches space between the water and the cover. They are frequently spooked and their way to escape from predator is to leap out of the water, so they frequently bump into the tank cover. Two months ago I noticed the largest one got DE suddenly on one side. The tissue that held the eyeb to the head on the upper edge was clearly stretched and wounded. It was looking down badly. And all this happened over night.
Now the wound has long healed. His DE got a little better, but it is still apparent.

Well, I think I just captured the evidence that wound can cause DE.
I was trying to move all 3 silver aros to my another tank, the one that had almost recovered from DE jumped again and it hit the tank brace very hard, then it lifted and landed on the carpet. The eye was damaged it can be clearly seen that it was pushed away from the eye socket a bit, the white tissue can be seen. And it is looking downward badly. I don't think it will ever recover from this wound. This individual is particular jumpy, sometimes it would jump when it detects a slight movement outside the tank. Luckily I still have the other 2 DE free.

Why?? Don't blacks bash their heads? and asians? and aussies? How come 10000 silvers get it for a couple of aussies, asians and no blacks??
