Good job on putting this together:thumbsup: Has a good basis for understanding what DE is. Since this is a highly debatable subject I'm sure it will end up with many a posts. For reference here is a pic of a 27" silver aro with severe case of DE,

Just wondering where the DE in the wild info comes from? I have yet to see any vids posted of wild aros with DE. There are however 5 or 6 youtube videos that show wild arowana.

There was that national geographic show on arowanas. The silver they showed had a really bad case of DE.

i would also like to see it. all the wild silvers i've seen vids of showed no signs of DE.
 
good thing my asian don't have DE but my silver right eye starting to fall down. One thing i noticed before a DE problem occur is that is starting to look like its going to pop up from the eye socket then it will gradually fall down. that is what i noticed when i frequently go to LFS around my hood. i've seen this on cases on asian arowanas as well but most of the time its only on the one side. but most of the time asians hardly get DE.
 
I do believe MsMassPoly has a monster over 20" without DE

Hmmm, you have not mentioned surgery for DE ... from what i heard it is quite successfull ... if somewhat dangerous (or a least sounds dangerous to the fish)
 
Good thread idea. Some thoughts of mine on DE:

It seems strange that while the closely-related jardini and leichardti aro's seem to be equally prone to DE, the closely related silver and black are most and least prone to DE respectively. I know in the past I've seen it theorized that DE is a CB issue; hence the largely farmed silvers get it, the WC blacks do not. But there are WC silvers in the hobby, and they get DE.

Is it true that pond-raised aro's don't get DE, or at least get it rarely compared to tank-raised aro's? If that's so it could well be a simple water-quality issue...but that also brings the "head banging" idea back into it, as the relatively more jumpy silver gets it while the often calmer black does not.

Really, was it the one with the silver carrying their young in their mouths?

This is just sort of like a first draft, once i find a better video of the surgery, I dont want to use the one where the guys slit the tail to fan it out more, as it might give some people some crazy ideas.
 
I don't really care for how that poster did their "surgery". Would it really have been that hard to do it right? i.e. aerated water flowing through the gills and a single tiny stitch* into the supporting tissues?!?

* - by stitch, I obviously don't mean fishing line. grr.

mmm, not that hard at all. We're only trying to put a thread through something behind the arowana's eye, and not knowing if we blinded it or not, no biggie.
