sexing Oscars

  • We are currently upgrading MFK. thanks! -neo
Best bet is to get a group of 6 and grow them out and hope that a pair is formed. Two years the female would be ready to spawn. Oscars are one of the hardest cichllids to sex, IMO, But venting is another way to sex um'.
 
You cant sex them, except by venting. Even if you get a 'pair' laying eggs, it is often two females. They will breed at about 8-9" which can be as young as 8 months old.
 
Males grow faster n bigger than females but they need to be same age only true way is just prior to spawning. There's a very fine line between breeding courtship n fighting oscars although there are exceptions. A lot of water changes!!gl
 
The easiest way to do this is to get as many as you can, in a tank big enough for them to reach maturity in. They will pair off. Keep the pair you like the most, and give the rest to your LFS
 
:iagree: with the others. oscars cannot be sexed by external features alone. they can either be vented or you can watch them when they spawn to see which one is the female, but as has already been mentioned it's not altogether unheard of for 2 females to pair together.
 
Yep, I've had female on female action with 2 pairs and maybe a third here coming up shortly.....
