Venting Lessons

[abiddle]

I recently read some info from Liz on how to vent fish.
The first picture is of a large oscar with what appears to be large vents.
Can someone please idntify the sex of the oscar.

The second photo is of a small midas with much smaller vents and a poor photo. Can anyone sex the midas? Or is it too young to vent?

Thanks!
