Drop eye cause by head trauma

[sbuse]

alot of those 1001 theroys behind de that dont envolve head trama are from people that say "i have never seen my aro hit the top so it cant be from that"

yet the suporters of head trama say this after there aro hits the floor or the top then instantly the aro gets it. even in the op's first post he states his black aros eyes are forced down after impact then recover. it is proven that black are resistant to de so it problibly wont ever get it. put a silver in the same situation and it will have it for sure.

another thing i have noticed from personal exp is that most aros have a side they will roll on and jump on. almost like being right or left handed. i have noticed that my aros that got de got it (at least at first) on the side they roll on, could be linked and help the head truama theroy. if the roll and jump to that side more often it gets hit more often and thus ends up with de on that side.

No, but there are those that make sense and then those that are easily dispelled with a little bit of research and logical thinking. Plus ad in the theories that have been developed because of ones personal experiences that are in common with that of many others, not just guessing there.

No offence, but I don't care about personal experience. It could so easily be misunderstood, that scientifically it's really nothing to go by. How can any theory make sense when there is no concrete evidence to back them up?

How would that make sense for wild aro's? If DE is caused by head trauma, and you say there is head trauma from jumping out of the water and crashing back down on one side, every single wild silver arowana would have it. They jump 3-4 feet easily out of the water and slam down on one side. Drop-eye would be a crippling effect on wild aro's and if it was caused by head trauma, then there would be no more aro's.

Then what use do you have of this forum? Most look to gain knowledge or advice as a result of a collective of personal experiences.

Wild aro don't slam into heavily weight tank tops or side glass, that would be the difference.

Firstly, I said "scientifically". In general, of course collective personal experience means something. In a scientific aspect, it means nothing at all.

Secondly, please read my post and the post I was replying to. He said the head trauma was from slamming back down ONTO the water. Not hitting what is above them.

Maybe you should be the one doing the reading, or at least trying to comprehend what your reading. Nowhere in sbuse's post does he say anything about the arowana hitting the water

I am no aro expert by any means, but after reading a lot of these threads, I think bad genetics make de much more prominent in aquarium silvers, and those in the wild aren't at much risk for it. The head trauma thing is really interesting and actually makes sense, unlike the whole lighting theory or fatty deposits behind the eyes... I'm pretty sure animals don't have fat behind their eyes.

Ahem, may I quote sbuse. "another thing i have noticed from personal exp is that most aros have a side they will roll on and jump on. almost like being right or left handed. i have noticed that my aros that got de got it (at least at first) on the side they roll on,". Now, by your definition he's saying his aro's are rolling....into the top of the tank? No, he's saying his aro's jump and then roll to the side and land on the water on that side. If he's saying his aro's are rolling into the top of tank then he has some slightly incorrect grammar, which would obviously be misunderstood.

I think I like the theory of the fish's diet being the culprit... high fat content or what not causing growth/fat to grow behind the eye.

Read a few threads about asia hobbyist doing surgery and cutting the fat from behind the eye to remedy the problem.

I dont think its always diet cause ive had 4 silvers over the years the first two didnt get the best diet and ended up with de but the last two got great diets and low fat at that, and they still got de my current one has it in one eye. I think its got to be genetics or inbreeding as the most common cause. Silvers being the most common are also the most mass bred. Like cichlids that are mass bred you will also see alot of deformities. Dont see aros being any different if bred the same way. Maybe one day there will be concrete answers for this. Could also have different reasons for happening so all theories are more than likely correct but not for every case.
