Hi you all.

Once I asked for suggestions on how to measure my Tiger Oscars without stressing them out. Well I went with the idea of using a measuring ruler next to the tank and taking pictures of them as they passed by.

I know there is some error of measurement due to glass-water magnification effect, so I took a few pics until I got a sample of them close enough to the glass in order to minimize the magnification effect error.



pic date is November 16th, 2008

That if the way I've always done it, I put a piece of tape on the glass place to where they feed, and you can get a good indication of how long they are.
