oooo I like the name phosphorus! hmmm we'll see. =) He's small compared to my other betta, but then again he's probably still young. My aunt said she got him 5 months ago. I really like him, he's so pretty. I love his fins. He seems happy in his new tank. I don't know what she had him in before. Now he's in a heated 5 gallon. He wasn't in a heated aquarium, that I know for sure.
