That's one of the, if not the, prettiest Oscars I've ever seen. What fantastic coloring!
I kept an Oscar when I was a teenager, and other than the fact that he can't get out and walk around he felt like having a dog. Such intelligence and personality on those fish; he wouldn't let anybody else feed him but me. If my Mom would try to feed him he would ram the glass lol! Unfortunately, he died of hole in the head.
That was, geez, a good 15 years ago or so. Truly a fish I could never forget and I do hope to keep one (or more) one day again, but you really do need a 55 gallon + tank for them. Honestly, I don't even think 55 gallon is big enough. Where is your school? Maybe we can get a board member to make a tank donation :P
