I brought a group of altispinosa from Washington last year and several
pairs are breeding now.  There are one-spot and two-spot individuals in the
group, both, males and females, so I guess it is individual variation.  I
noticed, however, that twin-spot males display a light blue iridescence on
the spots, have larger fin-rays and a more intense blue-red checkerboard
pattern on the distal areas of dorsal and anal fin than their single-spot
tankmates.  The twin-spot males are also slightly larger than their
single-spot siblings.  Is this a coincidence, or has anyone else noticed
this ?  Of course - Murphy´s Law - guess which fish were the first to breed ?
