here are two Hybrids with Black Bar Endler:
This fish carrys the MBAG ( Moscow Blue Additional Gen). MBAG creates the blue rump of the Moscow Blues. Sometimes it gets very dark, nearly black, so it ist often mixed up with Ni² (aka Tuxedo, Halfblack or HB). But everyone can differate both Genes. Tuxedo is not according to mood of the fish. If MBAGs are afraid they turns pale, the MBAG getting smoky.
Tuxedo is linked with a caudal pigmentation, such as Red, White, Pastell, Yellow.
Only HB Blacks and HB Blues are similar to MBAG.
But HB Blacks are not blueish and never pale when frightend. HB Blues have got the dark rump before they are adult. Already one day old HB fish shows the black of Tuxedo (Ni²) , MBAG appears only with the sexual maturity of the males.
MBAG females getting only smoky but never black at their body in old age.
A nearly roundtailed this Snakeskin Lace Black Bar Endler...nice!
cheers tobi
