I have a group of melanachromis cyanaeorhabdos, which in these parts tend
to be sold under the name electric blue johanni. I have read about the
differences between the m. johanni and the cyanaeorhabdos. Four of my
group have the typical light and blue stripes along their body, but the
fifth, a big male, also has subtle vertical bars.

I read on one website that perhaps a m. cyanaeorhabdos had crossed with a
m. interruptus. Has anyone else heard any more about this theory about
crossbreeding? And can you point me to a pic of m. interruptus?

Thanks,
Mark
