Ok, not that im an expert or anything but theres a big debate on drop-eye on whats the cause of it but heres my input on it

My 6 inch Black is currently in a 55g grow out tank. Occasionally it will spaz out crazy & go ballistic and jump like 5-6 times hitting the top cover for no damn reason or when startled accidentally by me

Just right after each incident, i literally see both of their eyes drop down completely & them it go back to normal

What u think guys?

I have a very laid back silver I have raised from 6" to now 24" and I have never seen him hit a top or side and he has one drop eye.. He's even in a 2800 gallon pool with no top.. I believe they get it from always looking down for pellets, shrimp etc that falls to the bottom while feeding. I think that in the wild drop eye isn't as common because most all their food is obtained from the surface and so they are always looking up... Could be why off but Is what I always thought anyway..

I thought getting drop eyes from always searching for food at the bottom is a myth ?
 
im not going to disagree with any1 on what they believe cause DE, but literally, i saw both of the eyes dropping downward for a good 30secs and then going back to normal. my black not only hit the top, but hit sides of the tank too..

i only if i had vid of it.. lol

but then again, DE, is more common in silvers than anything other aro. is it maybe caz more people have silvers which is more reported?

was it in a pool with no top all its life? just because you don't see it doesnt mean it doesnt happen. you do leave the tank unattended from time to time.

several members including my self have watched our aros hit then get de instantly after. looking down is not a cause. if it were then wild aros would have it. they have to look down for preds, food, and other fish. they dont just eat bugs out of trees.

on a side note were are you located and were did you find a baby black from? i have been looking for a while now.
 
A good friend had a LFS with a very larger Silver Arrow that had one drop eye, He had taken it in on trade. He had a small beach ball floating in the tank. I asked him what it was for and he said it was to fix the drop eye. It took time but it did work.

Apparently drop eye is from looking down all the time. Unlike in a tank where there is nothing to look up at in the wild there is reason for an arrow to look up .

Interesting... Think I may whip a ball in my pool then and see what happens....???? Bet it backfires and I walk out there one morning to find my giant RTC choking on it though.... :ROFL:
 
IMO and experience head trauma is at least a trigger for DE. It may also be the arowana can't recover from such because of the lack of use of the muscle around the eyes, which seems to be much more the case with silvers. Blacks, asians and aussies may be more apt to recover from the trauma.

As for the arowana looking down or up, well I have two perfect 27"+ black arowana, no DE. Neither of these two fish look up or down, their focus is forward. They may catch something with peripheral vision, but do tilt up or down to investigate such.

Wow wonder why beach balls work yet ping pong balls have been dispelled as a myth.
