I'm diggin the handle bars on that guy! a group of those guys in a tank and you'd think a group of bikers with pizazz came to crash a party!You should put some Poecilocharax weitzmani, these guys are small but very beautiful when they mature.
Anyways, I have seen those Sundadanio axelrodi blue at a local pet store and they are gorgeous. The tank they were in was a planted nano with a black substrate and background. The only thing that you could see of them from about 2+ feet away was their bright blue tops. Even up close, the rest of their body seemed to melt away. If she had some for sale I would have bought a group, but alas, she only gets them in once or twice a year-though she sells them for 4-5 bucks which is a killer deal imo.
