Yeap they were the ones that you had a look at Frenchy and had approached the guy on the cichlid forum about, sent you pics? I have heard that there were rather a few holding females around so there was definately a fair few, I just happened to buy a holding female and a dominant male, because I wanted to have them possibly IDed hence why I sent the pics 8) And didn't want to fork out too much ping to buy a group of them.
The lot I got this lot from were ones that came in as just straight Blue Melos, but this wasn't at the same time when Goldens started coming in again alongside the Johanni males. The shipment of Blue Melos were on the list for sometime and there were no Goldens/Yellows on that shipment.
The ones I have, have all bred true to the parents, identical, and they certainly look different to the good Johanni stock I have. The ones I have certainly match up to the maingano I have seen online, however, everything gets labelled Johanni when it's blue :roll: Bit of a pain in the behind really when nothing comes in labelled, saves confusion.
Oh and Dan yes there have been maingano in NZ previously, an old african keeper who has kept fish for a long time, had them here in Hawkes Bay and passed them on when he went out of fish keeping, he also had purple mbuna along with another guy here in the North Island.. apparently they came in some years ago.
