I still think it is genetic and maybe they just have more fragile eyes then other arowanas and the head banging just quickens the process?
I really have no clue lol. You could be right, it could just be genetics, or it could be the head banging. We wont know for sure until someone decides they have too much time on their hands and tries it. And to Hmoobvwj, for example, if a teenager were to break their bone, they would have no problem healing it, while if an elderly break their bone, they still might heal, but it might take a long time and might not fully heal at all. I think it might be the same concept.
 
i have another theory called the "lazy theory"Maybe they are just too smart and know there is no reason to keep looking up for food or hunting for it so they just relax because they know there master will feed them?

Why do only "Larger Silvers" develop DE...if the Head Trauma holds true (not saying that it doesn't)...wouldn't even smaller silver develop it, let's say at a size of 3"-7"....
You guys say it happens when they bump their head by jumping and darting around but even at a smaller size the silver will still do it occasionally....but never results in DE.....


Generally the smaller silvers have more room to move. Say you keep a 20 to 24" silver in your 180g. The equivilant sized tank for a 10 to 12" would be a 36" x 12" x 12" which is like 40g. For a 5 to 6 incher the tank would be 18" x 6" x 6":(

Also the smaller silvers are lacking in mass and power.
 
I have a 26" silver with one eye dropped. also have a wild caught at about 12" now that i've had since about 5-6" so we'll see.... i have a tendency to lean more toward genetics but my big silver has been through a couple rough times so it's hard to say with him.

This is a good point, I know the one thing Steve Irwin always tried to do with his crocs, is make them work for food.

Did you see the DE develop? I did see it with my silver, happened relatively fast. Others though have stated that it came on gradually. Now you state genetics, do you think wild caught don't get DE?

I thought of that factor before so I feed at random intervals everyday. Sometimes in the morning before work. Sometimes i come home for lunch from work and feed them then. Sometimes right after i get off work. Sometimes at night. Sometimes i feed once a day, sometimes up to 3 times a day. Sometimes even skip a day to make sure I dont overfeed. This is why rays are less troublesome lol, they look for food at every given moment no matter if they are hungry or not so I can use a feeding schedule.
 
I also found this on youtube. It shows a couple guys "fixing" an aro's dropeye. I dont know if it actually works or not, just thought I would post it. http://www.youtube.com/watch?v=4DTIAcO_aLY&feature=channel_page
Theres 4 parts to this, just follow the links that say arowana 2, arowana 3, arowana 4
And dont pay attention to the guy slitting the aro's tail, its supposedly suppose to make its tail fan out more when it heals, seems kinda creul to me though.

I honestly can't say. Sad but true. I knew about aro's and general fish care when i first got him but not near as much as i do now or near as much as yourself and others, and i won't lie he has been through some "poop" in his day and other than the one dropped eye he's perfect, even broke both barbels off clean and they grew back great, very long now. I would have to say that it was gradual because i can remember him not having it and well obviously he has it now. I don't know why or why not drop eye happens, seems there are many theories but from what i understand wild caught don't seem as apt to getting it as farmed. I could be wrong, just my understanding. I do also think that general care and diet probably can affect it one way or another. I can say i have put 6" on my wild caught and he has jumped once, and hit the lid multiple times and his eyes are still perfect. he is only about 12" though. We'll see. Just my $0.02.
 
Yea ive also heard of a lot of ppl slitting the tails on arofanatics. It is cruel in a sense but it doesnt hurt the arowana, and with melafix those fins can heal relatively quickly. Whether or not it works is another thing :) I certainly wouldnt do it.

I believe another link to DE in asian arowanas deals with tanning. When tanning Red arowanas, they place those fluorescent lights at near eye level of the arowana to allow the side of the fish to darken and make the color more vivid. However ive noticed many arowanas develop DE shortly after this procedure, and it makes sense. If someone shot a light in your eyes, you would obviously turn or look away. For arowanas the only way to look is down.

I dont think many people in North America tan their arowanas, as the lighting used (NAN lights) aren't certified to be sold here anyways. But just to bring it up since we are on the topic :)
