OB is a gene , Orange Blotch. at least one of the parents would have to carry the gene. Quote Link to comment Share on other sites More sharing options...
Boom Posted February 5, 2009 Report Share Posted February 5, 2009 How does a fish become OB. Is it a breed such as a Ruby Red Peacock? If someone can clear this up for me that would be great. I assume your talking about an OB Peacock? There are also OB mbuna, which are naturally occuring in Lake Malawi. Several different species of mbuna are naturally found in the OB color varient. The OB peacock is not naturally occuring, it came to be by man breeding a peacock with an OB mbuna. Here is an article that explains it more. OB Peacock Naturally occuring OB mbuna include: Labeotropheus fuelleborni (OB) Metriaclima callainos (OB) Metriaclima estherea (OB) Metriaclima zebra (OB) Tropheops tropheops (OB) Hope that helps you.

patrick Posted February 5, 2009 Report Share Posted February 5, 2009 In general, only females are OB. Blotch colour genes are on the W sex chromosome (males are ZZ and females are WZ). If a fish lacks the W chromosome it grow up as a male, otherwise it will grow up as a female. In most OB fish from Malawi and Victoria cichlids males are plain, females are blotched. In some species males are blotched as well. In these cases the males are actually females but they also have a gene that blocks female development, so they grow up as males. In some rare cases, such as with the vic Paralabidochromis choromogynos, the blotch coloration is more advanced with one gene deciding wether the fish is OB or not, and an another gene that controls the size and intensity of the blotches.
