Sexing Oscars

[Antwan]

I was told by my boss that you could sex oscars by looking at their gill plates, not their gill covers, but their plates. The gill covers are the part thats seen all the time and are the ones that go forward and backward. The plates are the parts that come from behind the cover. Anyway, he says if the edges of the plates are colored, there is a more than a good chance that they are males and vice versa. What do you experts think? If what he says is true, than I got a pair on my hands, and they sure do act like a pair.

Nope, the best way is just to vent them. Males though tend to be more streamlined while females tend to be more rounded. Also most males tend to have a nice indention on their head while the females heads are more rounded. I would vent however, that is the sure way to tell.

What the hell is venting?
