I have the same kind of problem, – as I mentioned I have too many harveyi males and other species have some times been a problem. I dont have very much experience with mixing, but at the moment I have some harveyi males and a linkei male sharing a 60 liter. That is going quite well really.
The linkei is visibly thriving better than in the smaller one pair tanks, he is big, healthy, up front, eager to feed and dont seem to be in competition with the harvey males, – never seen any confrontations between them 🙂
The harveyi probably do less good – the males of one species seem to have a constant thing going on where they have to determine who is nr. one, so I dont see all of them looking as if they are feeling quite confortable. For this reason a bigger tank is really good for this, the more space the better.
This tank is also inhabited by one lonely female albimarginata – without problems 🙂
