drop eye again....... wikipedia

[demjor19]

could the silvers just have inferior ocular muscles? but even this wouldnt explain the fatty tissue over the eye?

It is genetic. For me it is. I am gointg to write a book on the subject and earn loads of cash.

I don't keep black. But compare head structure of Silver to Jar and Asian, their eyes are more protruding, and are more close the top of head, hence easily get hurt. Their movement are more bursty when spooked, and they are weaker. Jar and Asian are more robust than Silver overall.

Another interesting thing is that when they get DE, they always get on one side first, that can be easily explained because they hurt their one eye at a time.

All you say does not explain wh blacks, who are like silvers, not stronger, ( if anything weaker ) eyes in the same position, don't have DE.....

Feeding
It is very important that you do not overfeed Arowana when they’re young, because as they grow, they might develop drop eye. Arowanas will eat insects, shrimp, pellets, live fish, beef heart, frogs, etc. The best diet for Arowanas is pellets, live crickets, and shrimps. Small feeder fish are often raised in poor conditions and can carry many diseases transmittable to predatory fishes.


the above comes from wikipedia..........any thoughts
seems to support the fatty tissue idea

I happen to agree with your assumption about over feeding .. i think too much food does bring out the syndrome of drop eye.. not cause it but help it along.. i really watch and limit the amount of protein too...too much seems to make them nervous and jumpy.. just my observations after having three Arows..not to say that young growing arows don't need extra food ..they do..all growing fish should have a varied diet and eat more often instead of more at one feeding..

how would this explain:

1) silvers are almost always Left eye..DE
2) the utube video of them removing fatty tissue from the asian's eye with de ??
3) dont most people feed aro's floating foods ??

1) I have had silvers with right side DE
2) I think that the surgery was uncalled for...
3) yes most people feed them floating foods but in a tank all they can generally see is the bottom of the covers, mine has almost lost all signs of DE in the pond where he can see up about 5 foot above the pond he has been in there for about 18 months now.... he looks great... oh and for your original?? about overfeeding I feed my fish as much as they want to eat so I dont think thats the prob atleast in my case

I will try and get some decent shots of him to show you how his DE has improved its just hard only being able to do it from the top and I am not gonna move him to a tank just for pics to much stress IMO for a pic

there is no such thing as too much protein

the diet can have a 60% protein level without any ill affect

it doesnt matter how much you feed either, the digestive system can only process so much at a certain amount of time. feed too much in one shot and not all of it will be processed in the gut of the fish. that is why it is said to feed small meals several times a day, so the digestive system can break down the smaller portions more effectively and utilize it.


i never did that though, i gave my girl all she could eat from day one
