Hello Mrs McKay,
There are three different types of Oscars. There is red, an Albino Oscar which comes in white and a Tiger Oscar which comes in black but it also gets orange or yellow on it when it gets older. The Red Oscars grow the biggest. The Tiger Oscar grows the second biggest and the Albino Oscar grows the least. I have got all the Oscars. I have four Oscars but the red one is my favourite.
