Hi, I'm new. I found this site while surfing for Oscar info. & liked what I saw & thought it might be a good place to find some help & learn more.
I went to Petco this evening w/ the intention of purchasing some large fish for my 150 gallon tank. There weren't any & suddenly I spied a single large fish & not really wanting it, but curious about it, I asked. I was told, "It's an Oscar that's actually up for adoption." I asked how much & received a quick reply of "Oh, it's free! Someone brought it back because it hadn't eaten for two weeks & is unhappy." So feeling sorry for it, I decided to take it. The petstore eagerly just gave me the fish, plus a free large plastic tank w/ lid to transport it. Even the feeder fish in the tank. I thought it sort of odd that everything was free, but why look a gift horse in the mouth, right?
The fish seems to like my tank. Instead of just sitting still on the bottom of the approximate 25 gallon tank like in the petstore, it is swimming around & I think maybe it likes me. I took some pics & showed an online friend who is an avid pet fan. Together we looked up information on Oscars. I see I have a very unique fish & I'm wondering what I've gotten myself into. lol
I came upon this & while I find it hilarious, I see I have alot to learn to properly care for this fish.

I think my Oscar is an Albino Tiger Oscar or simply Albino Oscar (not sure the difference, if any). I don't know the gender or age. I am a female w/ average sized adult female hands. My fish is slightly longer & wider than one of my hands.
Here are some things I am wondering:
1. Since Oscars supposedly should be in pairs, do I need to get another Oscar?
2. If so, do I need a specialist to determine the sex of my fish & then get an opposite sex fish friend for mine? And should the 2nd Oscar be the same size?
3. As a novice, how do I learn how to maintain the water levels...something along the lines of 'Maintaining Your Tank For Dummies.' lol
4. Petco gave me live feeder fish, but after reading about Oscars, wondering should I also give raw hamburger, tuna, salmon, earthworms, insects, insect larvae & other things?
5. How often should I feed my fish?
6. Is there a way to tell the age of my fish?
7. What other vital things should I know?
Thanks in advance for any help!

Here are some pics.
