No clue, she was in a tank solo when I picked her up labeled as Colombian Wallacii ... so I think she was a contaminent. I picked up a male from somewhere that ordered from the same wholesaler, but I don't think they were the same species (males are notoriously hard to ID without the females present. except notos and comps).
I have a group of C. regani from the Manacapuru area, near the main channel of the Amazon. I have had very little aggression issues with the 7 of them in a 40g though they will be transfered to my 150g coming in June after I move.
