I've got room for probably one more species in my tank and I was thinking of going with the Pseudotropheus saulosi for quite a while now. I've seen several local fish stores with them in the past. Well I stopped at 4 different places today and didn't see any. But a Petco of all places had the Pseudotropheus kenyi which look pretty similar but the colors are opposite. Of the ones they had most of them were blue and one was yellow. I was debating going with those but it seems like the saulosi might have a little brighter coloring. Is that true or just something that I thought I had noticed? I also like to have breeding fish in my tank. I just trade them into the LFS for whatever other products I need and I keep some. In the main tank I've got 3 fish that I raised from fry and some other fry that I plan on putting in the main tank once they get bigger. I've got one male and one female red face mac. The female was holding one time but lost them, I know I need more females but I can't find them anywhere.
