Oscars do grow at different rates so to estimate an exact age is difficult. However, I would say around four or five months. Is your other fish a pike cichlid? Unfortunately I don't know anything about these fish apart than they are South American.
It is extremely important to cycle a fish tank before adding your fish. Ammonia is very dangerous and will cause serious harm to fish even at small levels so if you have got ammonia present, I would get something like prime to neutralise it. In the meantime carry out regular water changes until your tank is cycled.
Thanks for the input OFL...
The tank was already cycled before I put the fish in. I think i just temporarily overloaded the bio filter adding the two fish at the same time.
I've had ammo chips in my filter (fluval 305) since day one, and the ammonia that i had for a bit was chemically bound (have the proper test kit) So yeah, i got a little greedy with adding both at the same time, but they're both doing fine, showing no signs of stress and most importantly my Ammonia and Nitrites are at 0 again with Nitrates steadily climbing.
As far as the pike goes, i dont know much about them either, it was sold to me as an "Orange Pike Cichlid" and the guy at Petland said they would get along fine, and they are.

They were in the same tank @ the store and i watched them swim around for 20 minutes w/o showing any aggression, so i was sold.
I've got a couple pics of my O, but the pike hides a lot and is still a little skittish around me, so pics of him are harder to get.
I'll start another thread shortly in the pics section for that.
Sorry for the Wall of Text, i get a little windy sometimes.
