This is my dear Lucifer (aka Lucy)… She is an Oscar Astronotus ocellatus, and believe me she has attitude like you would not believe. She is known to throw hissy fits, and attempt to attack people through the glass of the aquarium. She responds when I walk by and talk to her, she really is a great fish. I have had Lucy since October 23, 2004 and she has followed me everywhere I have gone. She is a great companion and is so much fun to watch, not to mention she is very beautiful.
