Dixon1990 Posted March 13, 2009 Report Share Posted March 13, 2009 Theres 2 on that site in a tank that looks around 200-300L and about 1.2m long and 50cm wide at the max. ITs horrible, But these ones actually look healthy :-? Quote Link to comment Share on other sites More sharing options...
ally07 Posted March 13, 2009 Report Share Posted March 13, 2009 They may look healthy at the moment, but that could just be due to diet. Once the aro gets older, you can start to see signs like a curved spine or gill curl more obviously. Another thing I've noticed about aros in pics even on this forum is that many have droop eye, indicating an excessively fatty diet. I don't want to imagine what their livers look like! I guess people like the idea of keeping aros without taking into consideration how much tank space they really need. Ideally the length of an aro's tank should be 1.5x the length of the fish and the width should be at least 1x the length of the fish. I wonder how often LFS ensure aros are going to proper homes before they sell them off at such exuberant prices.. Quote Link to comment Share on other sites More sharing options...
snookie Posted March 14, 2009 Report Share Posted March 14, 2009 the Aros dont seem to have drop eye though how crazy ! Quote Link to comment Share on other sites More sharing options...

ally07 Posted March 16, 2009 Report Share Posted March 16, 2009 the Aros dont seem to have drop eye though how crazy ! Drop eye isn't caused by undersized tanks, but by fatty diet, so maybe the owner is feeding the right food, but forgetting to provide the right living conditions.

livingart Posted March 16, 2009 Report Share Posted March 16, 2009 another reason for drop eye maybe that in the wild they spend most of the time looking up for food whereas in the tank there is really only a bright light or lid to look at for most of the day Quote Link to comment Share on other sites More sharing options...
evil_elmo Posted March 16, 2009 Report Share Posted March 16, 2009 i always thought there is no explanation for drop eye i have had a few aros in my time,all get feed the same things and some have DE and some dont it just the luck of the draw with their genes Quote Link to comment Share on other sites More sharing options...
A-town... Posted March 16, 2009 Report Share Posted March 16, 2009 yea i thought it depending on the quality of the fish and how vulnerable it is to getting drop eye. guess like discus getting stunted? Quote Link to comment Share on other sites More sharing options...
Dave+Amy Posted March 16, 2009 Report Share Posted March 16, 2009 almost tempted to buy them just b'cos they look so uncomfortable! Quote Link to comment Share on other sites More sharing options...

I don't think so. From what I've been reading and researching about aros (for my future dream tank), the main causes of drop eye are fatty foods resulting in a "pocket" of fat on the upper eye lid, causing the eye to "drop". Another reason is having a reflective bottom surface, or having other pets/ children running around beneath the tank, causing the aro to look down at its own reflection/ external movement. I don't know this from first-hand experience, but it's based on what I've read on aro care/ husbandry. almost tempted to buy them just b'cos they look so uncomfortable! I'm tempted to buy them whatever the reason! Aros are my dream fish, pity they are so expensive.. Quote Link to comment Share on other sites More sharing options...

David R Posted March 19, 2009 Report Share Posted March 19, 2009 evil_elmo is on the money, I've seen wild caught aros with de, aros in huge public aquariums with de, aros in tanks with no tankmates and only fed pellets that got de. ally07; good on you for researching the topic, however you should automatically ignore anyone who says that de is caused by an aro looking at its reflection in the bottom of a bare tank. Why? Go put a mask on and stick your head in the tank and look at the bottom..... Quote Link to comment Share on other sites More sharing options...

Dave+Amy Posted March 20, 2009 Report Share Posted March 20, 2009 Hmmm.. Interesting.. Maybe it's genetic? Some aros have worse DE genes than others? inbreeding/chance causes genetic defects to show more often...luck of the draw Quote Link to comment Share on other sites More sharing options...
livingart Posted March 20, 2009 Report Share Posted March 20, 2009 inbreeding/chance causes genetic defects to show more often...luck of the draw data i have read siggests that DE is not usually found in wild animals seems more restricted to tank raised fish Quote Link to comment Share on other sites More sharing options...
David R Posted March 20, 2009 Report Share Posted March 20, 2009 I've often wondered about that, as aros (not sure if this is strictly the south american species but I'd guess so) have specially adapted eyes for spotting insects in the branches above the water in the flooded forrest, perhaps putting them in a tank with several bright lights causes them to constantly look down away from the light. I'd like to experiment with pond-raised fish, but our climate isn't cooperating! My biggest questions about that theory is why it only happens to silvers and not blacks, and why it often only happens in one eye. In reality I think its likely to be a combination of things, including genetics and environment. Quote Link to comment Share on other sites More sharing options...
livingart Posted March 20, 2009 Report Share Posted March 20, 2009 yes i believe it is a combination of conditions, food types and genetic prediposition maybe the upward gaze means the bottom muscle on the eye is stronger and diet can accumulate more fat or fluid in the system around the eyes, weaker top muscle letting go first? living in a river as opposed to an aquarium would probably produce a fitter and leaner fish not couch potatoes frequency of food may be greater as well in the aquarium would be interesting to know how many aros with DE lived for awhile when younger lived with bottom fin nipping tankmates Quote Link to comment Share on other sites More sharing options...
herefishiefishie Posted March 20, 2009 Report Share Posted March 20, 2009 Has anyone been in a tank & looked out? Its weird. I am more a fan of drop eye being linked to being in a tank. If there is a reason. :roll: Frenchy Quote Link to comment Share on other sites More sharing options...
