George, Could the P. nicholsi be Pseudocrenilabrus nicholsi? This is a very beautiful fish. The males are very aggressive and do best with several females to disperse their energy. They also love to dig. Back in the mid 80's they were available but after a few years the stock seemed to have declined badly with only skinny ugly ones around. I have not seen them for several years. Dave ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@majordomo.pobox.com.
