Looking at the different stores that sell the demasoni, one store says they tend to move in groups and should be kept that way in an aquarium. Does anyone have have Pseudotropheus demasoni that are kept alone?
If they need to be kept in a group, how many females could i keep in my forty gallon if there are plenty of rocks and caves? I don't want babies, so getting unsexed fish is not an option. There is simply no place to keep them. If I have more than one, the would have to be females. If they do ok as a single fish, it doesn't matter and I can go ahead and get an unsexed juvi.

Thanks,
