Drop eye?

[zennzzo]

I know D/E is not a big problem w/Asian Aros,
but my Silver suffers 1 side Drop eye...
Anybody have a proven therapy to cure?

[Hendri]

try put in fiber tank to cure it..

most of arowanas will have drop eyes when raise in a tank.

[zennzzo]

here is pic of the severity of his D/E
Sorry having problems with upload pix...

Agree with chief :)

[zennzzo]

I'm seeing his eye looks to be more drop some days than other days...
If he is active swimming fast, it's more drop...just cruzing, not so bad...

[Bangi]

since most aros will have drop eyes in the tank... how do we prevent it? any tips/method that we need to take into account?

Ways to prevent DE:
- Covered up all surface except the front of the tank.
- use substrates at the bottom of the tank to prevent reflection.
- Place the tank at location where there are no small animals or children moving around as the aro will tend to look down.
- place some floating objects in the tank for the aro to look up.
- feed less fat diet as DE operation is to remove excess fat behind the eyes.

I agree. I think the reason for the DE in a glass tank (outside of diet and genetics) is that glass tanks permit light to shine brightly from above and the sides of the tank. Your aquarium light (on top) may be too bright. Then the also might also be suffering from the glare of the light from the sides of the tank specially if the tank is outside the house. Many of those who keep SRs tan their aros and expose them to daylight. That's why DE is a risk that they take to favor color development.

The aro will tend to favor 1 side while at the same time exerting effort to look down to avoid the glare from the top and sides.

So one possible theory I have is to cover the sides of the tank and put submersible lights at the bottom of the tank. Turn on the lights at 2 to 4 hour intevals only coz the good eye might get "lifted" if you turn the lights on for very long periods. Sounds wierd but Id try this if my aros will get DE also.

Thanks bro !!!

You are welcome.

Few more ways :

Throw the aro into a pond or Fgt May recover over months or year :)

Only wish the temp was above 40f here outside in the pond...:011:

If your house is big enough, you can place it in an in-house fiber tank.

Dear Brothers & Sister,

Is has been sometime not into posting. Well, agreed Question & Answer indeed.

Personal Opinion, mostly in Arowana will ED may also come with causes of many factor. I have try sereval time indeed for putting them into Fiber Tanks, the result was good but....... unable to last long.

Sometime to believe those Fat should be removed :022: but at own risk taken.

Secondly, Light effect may cause at ED easily, especially the reflection.

Lastly, Arowana may have ED which are normal cases but the most important is the beauty of Colouration......agreed ?

Hi my Brothers...
I am concerning whether the high of water will cause the dropeyes for young Aro? heard that we should increase the high of water month by month to prevent young Aro being dropeyes. Is this true ?
Some guys also advised me that young aro will be dropeyes if we feed him by foozen shrimp?

[Ruilong]

:up::up::up:good informations at here.....

[lvxback]

I believe its the lighting issue. If you do not turn on any lights at all, and
where you place the tack is totally dark. Turn on tank lights after 30 minutes,
you will see that when a normal aro without DE will have their eyes tilted down.

I believe they are trying to see where they are going. Is in the wild, at lease you have the moon.

I have had a small light turn on every night for my pg. So far so good.

IMO no one knows the exact cause of drop eye, i have played around with all the different methods and still confused, as to the answer. I have sold 3 SR at a big loss due to DE. You can view a young fish that has zero DE, and then follow all the info mentioned in this thread, 6 months later the fish has DE, no one knows why. Also it is strange why in most cases only one eye will drop. I think the genes of the fish has a part to play regarding this problem, but this is only a guess. For me if my Aro has severe DE as the one in the picture, i will sell and try again with a replacement.

[boonhlaw]

i guess lighting on top plays important part. however, i will not give up my fish just because it got DE.

[goldenboy168]

I think reflection of the bottom tank causes drop eye, and followed by the genes of your aro. So best thing to prevent is really avoid too much powerful lights and cover the bottom with substrates and control his diet.

I notice one thing that DE aro's are the ones left alone in the tank, so maybe putting tankmates (the bottom dwellers) will cut off the DE problem in 50%, this is my opinion becuase my 2yr old red don't have any DE at all, compared to my 4yr old silver who is left alone and suffered DE, and eventually died. So my opinion is based on my experience.

[hokevetss]

i agree..........

[million21]

Bcos they alway look side way course D/E. I dont think its the course of genectics, :011:
Try to keep the light inside the tank brighter than outside light(room light) all the time, may help prevention and cure. If u leave the tank darker than outside the aros more likely will look to the brighter side instead of looking up. Just my opinion, cos i fixed my slightly oneside DE... Its quite hard to get aquarium lights that stronger than sunlight isnt it?

[morphine]

Limiting space confinement in a glass/acrylic environment with regarding to width of the tank has been known and reported to be one of many contributing factors in DE.

It's a multifactorial condition in which genetics and environments both exerting their effects!

Arowanas living in a spacious environment for swimming about are much less likely to develop DE.

DE is a condition in which prevention is a much better approach then to treat it, because there is no guarantee of 100% recovery. Keeping it a pond or a large fiber glass tank have been known to give excellent chance for correcting the problem on its own if kept in such environment >6 months. However, there is no guarantee that DE would be cure for good!

[aroholic]

hi all

what i think is when u purchase the tank. buy the one special glass like where the police

question the criminal in the glass room. which is u cant see anything outside but the people

from out side can see clearly what is inside, like we all use to see in the movie. hope this is

the solution for the DE problem, so every1 can have a good night and enjoy there arowana

cheer

[inkh34rt]

good info here

[wadad]

put in a low tank with low water level.. feed floating food and less fatty ones.. don't put tank mates at all.. won't have DE..

[aroholic]

i use to have a silver aro round 30cm.i have him since 12cm. i put the flashing xmas light on the top of the cover to get the aro attention also i put some ping pong ball in the tank. feed him with frozen prawn and beef heart. and i have NO PROBLEM with the DE except the lower jaw is curve downward that the only problem i have and he stop growing from there but absolutely no DE at all. so what do try this. im not guaranty it work but i done that b4 and it work for me. b4 i have my silver i heard of the DE problem and i try to find that way to prevent it and this the way i do it.
the reason my aro have the jaw curve downward was i reckon bcos i keep him in small tank for long time due to no room for the big 6ft x2 x2 tank i have now.

[BOOMERANG]

thanks for a healthy discussion... i had my silver aro in a tank with substrate when he was small... but it didn't cure the DE...he is now at my big tank with polycarbonate bottom plate....and it doesn't help either...one thing for sure, his DE doesn't get worse either....

yes, have heard a malaysian fish farm put the lights at the bottom for some other purpose. but turns out that all the full grown aro in that tank have perfect eyes. My thought is that, maybe for silver they are more sensitive to lights than the asians, so they drop eyes earlier. for asians, even though they are less sensitive, but still have the problem after years.
