Unfortunately you can't keep 2 Oscars in a 40 gal for long. The tiger will be killed. You can easily house 2 females, but you are going to need a tank of 120gal "minimum".
fetto, have you ever seen a full grown Oscar in person? When petsmart sells them "SM" and "LG" versions - "LG" maybe big for them but in reality they are only 3" long,- Oscar's can and WILL grow from 12"-18" When / if yours grow to full size (in about a year) you will have two fish too large to turn around in their own tank. And with age comes aggression. Couple that with a tank 4X Too Small = Destruction.
What I'm saying is, they'll most likely be much less aggressive / temperamental in a much larger, well aqua-scaped aquarium.
Good luck.
thanks. Yes ive seen fully grown oscars before larger then my head, and im aware the 40 gallon is quite crammed for 2 oscars. Right now they are about 4-5 inches, they have def doubled from when i got them. Yes i know how petsmart lists them, but i always wanted oscars, and i needed to clear out my convict tank. So the orignal intentions were to let the oscars clean out the convict tank so i can start over. But then the oscars started getting beat up, so i threw a red tail in there too, and the convicts started beating him up. So i pulled my extra 20gal high tank out, threw the convicts in there, and gave the oscars and rtc the 40. They are doing well right now, and ive noticed that the white oscar beats up on the blck oscar, and the black oscar beats up on the red tail, and the red tail chases the white oscar, so its a viscious circle lol.
Ive been going through craigslist religiously looking for a larger tank to upgrade to. But the few 100 gallons ive seen were mis sized, or cracked, and the 150+ gallon tanks ive seen were too overpriced, or came with no equipment other then the tank for an arm and a leg.
Or i was looking to get a 75 for my african community, and giving the oscars, the 55 gal the africans are in now, until i can get my own place with my own monster fish tank
I hope this doesnt come off sounding cruel, but this is my first attempt at oscar keeping, africans 8+ years, so i expect to learn by trial and error as well
