For the most part, I agree with this post. But one issue we have in the hobby is over crowding of tanks, mostly by people just starting out. If someone would state something like "I have had my 4 mbunas for a year now in my 55. My water levels are all fine and I do 25% water changes every week-end. I am thinking of introducing a couple more into the tank, what do you all think?". You can tell the person has some experience at least and that they work to keep the tank stable.
No offense to the OP (you have 130+ posts, so I assume you know what you're doing!)...but if someone asks "How many African Cichlids can I keep in a 55?"...you don't tell them 10-12!
By the time you add enough rock, structures, plants, etc to establish territories, your fish will be stuck staring at each other. At best, you would be doing massive water changes frequently. It would take a ton of work to keep a tank like that in check...which would only add more stress to fish already stressed out.
I don't know obviously just how crowded fish are in the wild, but from what I have read, Lake Malawi Cichlids can get as dense as 20 fish per square meter. This is approximately 2 fish per square foot...or in this case, 8 in a 55 gallon. But, in the wild, these fish have 11,430 square miles to spread out, not to mention, lots of space overhead and below
Not saying it hasn't been done before, I have seen it. But I still think its best to be very conservative when passing out stocking advice.
Take care...
