If you look real close, the one on the left has its tube out too, they are both males Ive had since they were 1". They havent seen a female since they were fry, which I feel a little bad about. They were just recovering from a bad dose of septeceimia at the time this was taken, and had external bacteria problems as you can see from the fins on the one on the left. Ive been trying to find a 'single' female from a breeding pair but have had no luck so far.
They dont like being seperated even though they do lip lock often and nearly push each other out of the water when the tank lights go out, but I have had them since babies so if they dont do serious damage to each other, I'll keep em together for the moment...
