Yes and no. There are 2 different locations where M. boesemani are found and they are sold as such. The ones found in shops are just the common original boesemani. The 2nd variety (Aytinjo) will only be obtainable from breeders who have them.
In addition to this, there is a lot of variation in colour in the original varieties that has been caused by people breeding poor coloured fish. So some boesemani will be nicely coloured and others not as bright.
Finally, the males don't show full colouration until their second year.
