I just got this little guy today. I can tell he is going to be a good fish. Very lively and likes to watch me as I have him on the table beside my bed. I'm sure he is happy to not be in that little dirty cup anymore. I got him from Petco and chose him because I rarely see white Betta fish and I thought he was gorgeous and unique! The cup he was in said he is a "half moon". Does anyone know what his coloring is called?
