Dropeye Experiment?

[midnight]

Now... I just need to figure out where to get a 8'x2'x'2 bin

[FONT=Arial,Helvetica,Geneva,Swiss,SunSans-Regular]3' x 2' x 8'[/FONT]
[FONT=Arial,Helvetica,Geneva,Swiss,SunSans-Regular]300 gallons[/FONT]
[FONT=Arial,Helvetica,Geneva,Swiss,SunSans-Regular]77 lbs.[/FONT]​

[FONT=Arial,Helvetica,Geneva,Swiss,SunSans-Regular]160.50[/FONT]​

Still would need the pellets in it's diet though

why?
i never have never will,use pellets and my aro is quite nice.

It could be that they are stressed from watching people and moving objects by their aquarium

i will solve this one for ya
theres nothing different from an aro looking out a tank then him looking out in the wild.
he can look left and right in the wild just like in a tank.
and theres moving objects in the wild.
get what im saying?lol

Wild arowanas usually don't get dropeyes

have you seen in water pics of a wild aro?

Worst case scenario? I get an arowana that I have always wanted to keep... with a dropeye like every other arowana keeper.

if ya want one get one.dont have to make it an experiment.lol

Plus you can gutload the bugs too with the pellets...

Can't really debate with that. However I would not be too surprised if they do better in a top-bottom setup than a see-through setup. I know some reptiles are more high-strung when kept in opaque setups than see-through setups and some of them took to having bizarre behaviours such as head-tilt all the time. A lot of people who keep them that way say it is normal, while the people that use see-through setups say it is not. Take your stance.

have you seen in water pics of a wild aro?

Seen ones that are caught...

Thought it might be fun to see the result... plus I think arowanas are entitled to their natural behaviour anyway!

Well arowanas can't or wont get drop eye in there natural environment and one reason is because a well known cure for current drop eye is to put the arowana in a pond and within months there eye will get back to normal.

BTW that big tub you posted for 160 something, is it meant to hold water for long periods of time? sounds like a good tank for hospital/quarantine.

out of water pics im guessing.
alot of fish actually get de when taken out of the water.lol

Tough high-density polyethylene tanks that resist cracking or breaking even in cold weather. UV inhibitor used to prevent deterioration from sunlight. Threaded plug in all tanks for easy draining.

sounds like it would work great,i dont have one tho.


and on the de,im just curious why mine only has de on one side lol

I don't claim to be scientific. PERIOD. I am doing the same thing what some varanid keepers did to figure out what was wrong with their husbandry -- replicate their natural environment within reason (equipment and space issues), then work backward from it.

Now we can conclude that:

- Wild arowanas usually don't get dropeyes
- They are insectivorous (diet)
- They don't live in glass boxes where they can see out (pond versus aquarium)
- The water they come from is usually murky
- They naturally jump 6'-8' high (use of nettings and PVC to prevent head trauma and flopping on the floor)

Although we have to conclude that Silver Arowanas and Asian Arowanas are more likely to get dropeyes than the other species of arowanas which is a whole another ball-game that we would have to figure out separately.

as adults that is incorrect, the bulk of there diet is fish, there arent enough insects available to keep up with the sheer bulk of an adult arowana ( note that there is HEAVY competition in the rivers and flooded rainforest from which they come so insects could not sustain a population of adult and semi adult arowanas in a river.) fish are the most adundant source of food for them in a river system. insects suits hatchlings and juviniles fine though.

i dont know about you but every wild silver arowana ive seen either a photographs or in video documentarys was in cystal clear water with a nice amber tint.

try this as i am curious

raise a juvinile in soft acidic water its whole life and see what happens.

I am a firm believer in the head trauma theory. The two cases of de I've seen immediately followed severe head trauma-full blown Aro typical spazz out, one hitting the top of the lids, second one dove into the bottom of the tank, hit the top of his head on a chunk of marble and blammo! instant overnight d.e.

Del-behave yourself or else you're gonna get another slap!!! This is the most common subject I think ever debated on this forum, for good reasons. We don't KNOW for sure, and discovered long ago, after heated debates and having our threads shut down cause we got too passionate, that we also all don't agree on the same theory.

I commend and support anyone who tries anything to further educate us or ultimately find out why, how or best yet, how to stop having ole one eyed Jack staring at ya from across the room!

Alright... then why are South American arowanas evolved to jump 6-8 feet in the air, are still primarily surface-feeder and often found in shallow water? I will go through some ichthyological papers on the diet of arowanas later.

Have you even seen the size of South American cockroaches that American herpetoculturists keep to feed big lizards?

My silver(female) was raised in very soft, 6.4 pH water up until it was 18". Once I moved her to the 180g I found I couldn't/wouldn't produce enough R/O water to do 50% weekly changes. Has now been in moderate 7.4 pH water since may.

To me the DE is a result of many things. Maybe head trauma is the trigger and wild silvers also get it, but something with captive silver keeps them from recovering from it. Could be diet(most silvers I beleive are grossly overfed), lack of need to look upward, water parameters or maybe they are all just really sad. We just really can't tell.

Best thing we can do is provide them with as much swimming room as possible, pristine water conditions and a healthy varied diet.

I had one whack his head, get a bit of d.e., then recovered a bit then when I put feeders in, it got worse and became permanent. Now, I will never use feeders, I saw a pretty direct correlation.

FACE IT-We are taking wild animals out of their native habitat and caging them in reality, no matter how big the tank, into a small area that is unnatural-maybe the de is just somehow the beginning of an evolutionary process to accommodate new habitats.
