Stop or slow down drop eye?

  • We are currently upgrading MFK. thanks! -neo
I have tried to find scientific articles on this with no success, if somebody has an article or a link, please share.
IMO, nobody seems to know the cause/reason for sure, my take is its genetic in nature, I don't think I have seen a large (2') silver that does not have it. I would be surprised if it is merely a fatty deposit, why would the distribution of fat lead to (in almost all instances) it being deposited behind one eye only?

The reason for drop eye on one eye could be because most fish are either right or left sided(much like humans typically being right handed),most fish species examined are left sided
 
My silver has one dropped eye (right). The other side is fine, doesn't bother the fish, or me.
 
Cover all sides of the tank with white paper, dim/reduce lighting, slow flow, reduce feeding, and minimize activity below the fish

I agree...there are a lot hypothesis, but I've not come across anyting concrete. If you believe this is most common in various Silver species, then Australian Arowanas and little to non in Asian Arowanas, then it points to genetics making them susceptible and not simply being in tanks or diet alone.
 
Are we sure this doesn't occur in wild populations, has anybody ever done a controlled survey on this?
 
I read somewhere that if you put bright coloured ping pong balls in the tank it forces the arro to look up. Dunno if that's a wind up tho.
