Good luck with them! You will not be dissapointed in the interaction and personality of these fish. They are absolutely wonderful and have more in common with a dog than a fish. But as Star said, when they hit about 6 inches (teenagers) they may turn to hate each other. But on a lighter note, things to look forward to: THem greeting you at the glass when you get home, wiggling their bodies in hapiness to see you, eating tasty treats from your hand (may have to teach them to but they eventually will when they are completely comfortable with you) and the enver ending drama. And by drama, I mean them getting mad and acting like they are dying because you changed the water, added a new ornament, went in the tank to scoop extra food out, oh and of course, just being late from work lol
When you do get them, do not be alarmed. After you acclimate them, they will probably spend a few days laying on the bottom of the tank.It is very normal for an oscar to do that in a new environment. It is also what they will do with the aformentioned events. The famous oscar sulk.
