That is 1 of 2 red oscars I got from Petsmart. I bought both of these guys in July of 2010. I got the smallest size possible which was right around 1". They started out in a 75g along with some other green terrors, jacks and jag. They only lived there for a month, when they got moved into the there current tank (72x18x30). They are living with a jag, breeding pair of jacks and 4 green terrors. All the other fish are around the 4" mark. The biggest oscar is right aroudn 7" and the smaller one is about 5.5" They get fed as much as they can eat and their diet is krill, shrimp, cichlid staple and cichlid bio gold. Tank is filtered by 2 xp4's and has 2 50% water changes weekly.
