Drop eye cause by head trauma

[eklikewhoa]

Agree, The most plausible theories is genetics and diet, IMO.

 

[1bigdovii]

Could also be possible genetic and fatty deposits are linked. Possible bad genetics cause the fat and bad diet speeds it up. Thinking back on my two aros that did not have the best diet i believe they did get it faster. Trauma could cause it but it would seem if trauma causes your aros eye to drop that it would correct itself once any possible swelling is gone, unless maybe there is nerve damage. If it just all of a sudden shows up then it was probibly injured cause i could watch it slowly happen over months in my aros, and it think the first two they were like 12" when it started. My last two at over 16" before it started.

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'm sure Scott will chime in and help you understand that which you don't. Until then, they're in tank the only thing they hit when they jump is the top, no room to jump out of the water and land back in it. He is stating that they tend to roll to one side as they jump, therefore leading wth the side of the head that the DE develops.

I read his post again. Nowhere in there does he state that there in a tank. But never-the-less, from what I thought his post meant, that was my opinion. The way the post is written, it's not unlikely I mis-understood it. I'm just saying that, if DE was caused by head trauma, and head trauma came from hitting the water's surface side-ways....well, that that would not be possible.

brian your right on my meaning about the jumping and rolling.

to gandalf

i'd have to kick myself in the nuts if i was trying to say it was from hiting the water. they would have to jump a few stories out of the water and fall back for that to be a hard enough hit to get the required trauma.

i do have bad grammer i failed english several times and i am using a smart phone. that all combined with me having huge hands and little to no feeling in them from nerve damage it makes it hard to type on this damn thing. brian was right about what i was saying.

being a hobbiest and looking at all my threads all my personal exp with aros would be in a tank. ill just bite my tounge and leave it at that.

another interesting thought is that de could be so crippiling to a wild aro that is why they are not found above or below rappids or water falls in the river system. some things i have been looking at myself. i originally thought it was just based on there prefurence to slack water but my aros have all enjoyed the current in the tank. it could just be the captive fish syndrome but outside of my in tank exp i think that the head trauma could be one contributing factor in the range restrictions of silver aros.

the only thing i have against the genetics theroy is that asian aros and arapimas are farmed way way more and have been for way way longer then silvers so they should also get de just as fast or faster/easier then silvers. i like the gentice theroy because it could just be in there genes all around to get it. i have had wild caught silvers before and they got de just like my farmed silvers. it could just be in there genes.

back to my jumping on a side thing, if you watch wild aros jump they for the most part go to one side of their target and curl over to get it, thus minamizing the chance of hitting the limb directly. this could be an adaptation to the de. eg the aros that did this passed there genes on and the others died out. they cant do this in a tank so they get the full force. all things i have come up with in my researches over the years.

Your right, and why would common sense apply? Not like keeping arowana in a tank is a common practice, right?

It's down the species boys i have had silvers and every silver had de then it's red 1 outta the 2 reds i have owned has had de and alotta friends reds have de but i have had 3 gold arowanas none of them have had de i Dono what it is diet,water
,hitting the tops but I'n some species it's very common and I'n others never even seen 1. And i gut load my gold pure earthworms everyday and that's pretty fattening food.

Glad that you said that. For one, I don't think keeping an arowana in a tank SHOULD be common practice. If you want to house it there for the first year or two thats fine, but unless you have a 10x5 tank then it's just not going to work. I do not understand everyone saying 8x3x2 is standard for silver arowanas. We're dealing with a fish that can and WILL reach 3 feet in the aquarium, possibly 4 feet in a pond. So no, keeping an arowana in tanks shouldn't be common practice; keeping them in pond should.

Looking forward to your pics of the 10x5. Or are you one of those "what I'm gonna do" guys?
