Willy Posted September 15, 2004 Share Posted September 15, 2004 hey guys, i think my aro is begining to get drop eye on left side, its not that bad at the moment i dont feed it anything fatty, just prawns with shell and bloodworm, pallet its about 30cm has anyone kept one of these in a tank and grew it up without it getting drop eye? Is this even possible? what tricks can i use? Link to comment Share on other sites More sharing options...
r.d.m Posted September 16, 2004 Share Posted September 16, 2004 have you got gravel on the bottom? if they can see their reflection in the bottom they will develop this condition Link to comment Share on other sites More sharing options...

punie Posted September 16, 2004 Share Posted September 16, 2004 People i know, just float a ping pong ball on the surface to prevent such occurences, whether it cures it.. i'm not really sure! Cheers, Jerome Link to comment Share on other sites More sharing options...
Ducksta Posted September 17, 2004 Share Posted September 17, 2004 IMHO they are all old wives tales (tails? ). I believe (and not through experience, only research) drop eye is most definately caused by improper diet or water conditions, much like HITH in large cichlids. I certainly dont believe it is the fish trying to look down at the bottom or any such thing. Also, from my years on several forums dedicated to aggressive and predatory fish, it seems the condition is irreverseable in most cases. However on rare occasions people claim to have fixed it by improveing filtration, tank maintenance and diet. So my advice would be to keep the water pristine, crank up the filtration and only feed high quality foods which match an arowana's dietary needs Link to comment Share on other sites More sharing options...
Alex Posted September 19, 2004 Share Posted September 19, 2004 In my opinion it's genetics. Ever seen a Jardini or lecihardti with drop eye? only Asians and Silvers, which are heavily farm bred, with small gene pools. Food for thought. Link to comment Share on other sites More sharing options...
Willy Posted September 20, 2004 Author Share Posted September 20, 2004 I agree with u alex, someone on qld cichlid told me he tried to cure it and put it in pond, it was cured but when he put back in tank it became drop eye again. he told me same thing and thats genetics, farm raised.

Guest african-au Posted October 17, 2004 Share Posted October 17, 2004 i'm with alex i beleive drop eye is genetic as asian arow's & silver arows are farmed! but just to be on the safe side my arowanas are fed quality food lean & mean chris Link to comment Share on other sites More sharing options...
Arrafanatic Posted October 17, 2004 Share Posted October 17, 2004 Hey Willy, I raised a small Silver Arowana from about 10cm to 45cm about 2 years ago without it developing drop eye. I strongly believe that drop eye is caused by incorrect feeding of fatty foods like feeder goldfish, as well as people keeping them in tanks with just a plain glass bottom. This makes the arowana see it's own reflection on the bottom of the tank, and because they do not like the comany of their own kind, it forces them to keep an eye on the 'other' arowana that they appear to see in the tank. To avoid this, just simply keep something on the bottom of the tank. ie. gravel. This will abolish the reflection and more importantly remove the need for the arowana to look down and focus on the bottom of the tank. Thanks guys Arrafanatic Link to comment Share on other sites More sharing options...
Alex Posted October 17, 2004 Share Posted October 17, 2004 The old no gravel myth is completly false. I raised all my Jardini/leichardti in bare bottom tanks, due to bare bottom tanks being far easier to clean and maintain, none developed dropeye. Why is this? I have raised many silver arowana's, in tanks with a substrate and feeding only the best foods. Most developed drop eye. Why is this? If I had the time or money this would be something that I would put some time into researching, but i don't. The facts simply speak for themselves. - Arowana species which are not heavily farm bred (leichardti, jardini, blacks) never devlope drop eye, or if they do they are in the 0.001% that do. - Asians and silvers develope drop eye about 75-80% of the time in my experience, and by talking to other arowana keepers, especially ones from OS. - None of the myths add up. Alot of arowanas in bare tanks dont develope drop eye. Alot of well cared for arowana's in tanks with substrate develope drop eye. I could yabber on about this topic all day. But I think at the end of the day the facts speak for themselves. If you manage to get a silver over 16" without it developing drop eye in atleast one eye, consider yourself lucky.

Alex Posted October 17, 2004 Share Posted October 17, 2004 i think we will just have to wait and see how these guys turn out Link to comment Share on other sites More sharing options...
johnwilly1000 Posted October 17, 2004 Share Posted October 17, 2004 cant belive u have 3 beaut silvers. i planned on getting more than 1 arow when i first started but thought they might attack eachother and that would ruin the fish. inform us how yours are doing?

Tam Posted October 18, 2004 Share Posted October 18, 2004 john's developed a severe case of drop eye lol joking mate i think its alright to put in 4/5 of them at the same size and time... with other fish to make it more crowded... abit of tear here and there until they sort themselves out... the hard part is when they grow bigger...

Glacius Posted October 18, 2004 Share Posted October 18, 2004 I dont think saratogas get drop eye anyway, Ive had 7 all different sizes in bare tanks or graveled, I think silvers get it most maybe due to genetics........... yea Ive had from 3-7 20cm saratoga L with one 60cm leicardi and other fish no problems just need to populate the tank. Even huge arowana or saratoga Ive put little 6cm parrots in and nothing happens they attack by colour and if populated even better. Link to comment Share on other sites More sharing options...
