What size of a tank did you have Blue Phantom? I plan on keeping a pair of them, i am just in the process of finding my male a female. So far out of the five, two are definate males. The large male and one who is now the sub dominant one ( the one who tries it on with the others when he isnt looking). A possible male, still a little small. And two possible females, the smaller of the two i am almost sure is a female, and she is much more colourful than the larger, so i hope the dominant male pairs with her.
