They look just awesome. Good for you. I'd honestly be excited myself if I received those fish.
What's the pH of the water you'll be keeping them in? There's an experienced tanganyikan fish keeper on the cichlid-forum that swears that keeping tropheus at pH 9.0 - 9.4 really makes a difference, whether captive-bred or wild caught. As an experienced tropheus keeper yourself, what's your take on this?
On the subject, I've always kept my Frontosa in sodium bicarbonate buffered water, which only goes up to a max of 8.4 pH. I've only recently started including enough sodium carbonate in my buffer to bring my water up to pH 9.0 and I will say it has made a postive difference in how comfortable my Moba are in their activity level and being slightly less shy. Note that my Moba are wild caught.
