wonderful feeling, isn't it? you are very much
excited and couldn't wait till you oscars lay
their first eggs.
since you are not sure how old your oscars are, and
unless the rituals turn out to be hurting each other,
you are probably lucky enough to have a pair. necro is
right in saying 12 to 18 months old or size of 8 to 10
inches long, but if your oscars had been stunt their growth
before you have them, then nobody could tell if they are matured
already and ready to spawn. keep cross your finger.....
