Wow, awesome shots Thanks for the photos! I have saved the lot, but now that I have seen what a Male BGK looks like for sure, I can see I got two females I see exactly what you mean by the head shape & the pot belly
Here in Victoria (Melbourne AU) the LFS mainly sell juvenile BGK's. However I will try swap or buy a male BGK trough the local forum. I have seen one 12" BGK in one of the LFS here yesterday. I recon it's a male, but it's not for sale & I don't think they do STUD duties The poor 12" male is stuck in a bow tank around 40gal or 150liters with other fish... Here is my 8" Female BGK, I have not been able to get a good shot at the 10" girl, but she looks about the same
The 8" BGK girl seems to be a darker black in shade than the 10" BGK girl & the eyes are clear black instead of opaque like on the 10" girl. I've optained both in the last couple of months & the opaque eyes must be due to previous water conditions or due to inadequate diet. Will see if it clears up.
Cheers
