Stocking a Lake Malawi Cichlid Tank

I recently acquired a 50ish gallon bow front tank with a penguin pf0350B filter, and I’ve had it running for a few days now, and I’m now thinking about what I want to put in it. I really like the idea of a Lake Malawi Cichlid tank, but I don’t know much about them. I’ve heard that fitting as many as possible into one tank, usually about one fish per two gallons, is ideal for minimizing aggression, but I can’t imagine fitting 25 cichlids in my tank. My source is:

https://aquariumscience.org/index.php/17-4-lake-malawi-cichlids/

which admittedly does say that the article is based off of personal experience, but it sounded like this individual is pretty knowledgeable in terms of cichlids. But just in case, I wanted a second opinion from the cichlid community on stocking my tank, the best providers of these cichlids and any other advice on caring for them if I choose to follow through with the tank setup. Also, if it helps, I would probably copy the above sources “peaceful” tank setup in terms of species, consisting of labidochromis, psuedotropheus acei, cynotilapia zebroides, lethrinops, and peacocks.

Thanks!
