Del, it's funny you posted that, I noticed exactly the same thing recently with the reflection.

2 sheets of glass underwater generate a mirror, if you look at the tank normally thorugh the front, the sides are mirrors. But of course they are not mirrors to the fish, they can see out of them. So can you if you look at the tank lengthwise.

I looked at the aro tank through the top with no cover, and on the patches of tank with no sand, there was no reflection at all, none, only the brown card underneath.

So this finding should conclusively prove that drop eye is at least not generated by bare bottom tanks. And if bare bottoms tanks is your thing, at least you don't have to worry about any fish staring at their reflection.

But you do not see a reflection of the back glass if you look through the front, the reflection is caused by the third glass aspect. You only see a reflection if there is another piece of glass directly opposite the glass your look through.

ie in a fish tank it is the back pane of glass that causes the reflection to the sides and indeed the bottom if no susbtrate is down. and for the same if you look at the underside of the surface of your water it again is the rear pane that causes the reflection.
 
Del, thanks for the info I found it a great read as I have been asked if I can re-home a 27" Silver Aro the person can no longer keep the aro due to size and asked me to take it for free. Wooo Hooo

2 Questions though, firstly

Jumping

My Cabinet is of wooden structure completely housed so I have no concerns of him escaping however the lighting tubes are exposed would this be best to protect them and ig so how????

secondly,

Filtration

In a 200 US Gal Tank would a single external filter capable of 132 US Gal would this be ok if only the 27" Aro is in the tank.

Thanks Very Much

are these supended on a conopy or are they resting on the aquarium?

you could use a peice of a acrylic to cover the tubes, id feel uneasy about glass since its alot stiffer and impact may cause heavy injury and if the fish is big enough or hits right, may shatter the glass.

secondly,

Filtration

In a 200 US Gal Tank would a single external filter capable of 132 US Gal would this be ok if only the 27" Aro is in the tank.

that should work out fine, whats the gph rating on the filters?

Thanks Very Much

Thanks for the information. Research always seems to be key. I do have one thing I would like to add to the disscussion about the droop eye. I had a buddy that had a problem with a 28 inch silver arowana and he ended up putting a lair of gravel one the bottom for insurance but most importantly. He had tried to distract his fish with a red ping pong ball, witch now seem to be a toy for the big guy. Anyhow, many months down the line the droop eye did seem to almost dissapear. Given that he had be more responsible with the diet of the fish and also that it seemed that the arowana was some what interested in the red floating thingy. Well, it will help anyone out there is the main thing. Never hurt to try something new.:nilly:
