Marvelous fish!! I have two male and one female Golden Killis and they are very Pike-like in their behavior and attitude. Not only are they stunningly beautiful, - they are absolutely fearless as well. if I put the net into their tank and transfer them to another, they actally seem to enjoy the adventure - they swim right into the net every time!! The Female and males do their mating dance often, but so far no babies - I didn't buy them to breed them, but who knows what may happen. They have eaten a white cloud and a cardinal tetra or two - but I have learned to keep them only with fish above a certain size!
