I just got my little male firewag sunset platy, ember. he is very skiddish right now, and is hiding with my pleco in the plastic cave. mostly from me, and from the betta. when ember went into the tank, the betta flared at him and chased him, then tolerated him, then chased him again, as if he couldn't decide if ember was another betta, or something else. in the end, blue (my betta) decided that ember was not another male betta. he is still very nervous, though, and I think later i'm going to get 2 female platies to keep him company...
