Yes, for the millionth time, you cannot accurately sex the super reds with markings. Mature males and females will show varying degrees of spotting and worming on the face.

Venting is the best way for super reds. Rotkeils can be sexed by markings but you'll have to wait until they're 3 - 4" and the mature coloration starts to develop.
Does anybody have pictures of what a male vent and female vent looks like? I can't vent a fish if I don't know wat too look for.
 
Both of my reds have marks in between the eyes, wondering where you get the idea for that rivers? I've had eggs laid.

That is just what I have read. Most of the standard ways of sexing severums don't hold true with reds. But I have read that this holds true most of the time not 100%. Venting is the only way to know 100% but mine aren't big enough to vent yet.
