Basically I beleive its luck of the draw, my combo has worked well and even adding new fish has not been a problem. I've had three different convict spawns, without much problems also.

Here is my original 150 gallon cichlid tank, which was set up in June '07

It's 96" x 18" x 21" and is filtered with a large w/d sump and a xp3. The occupants are 10" & 6" Jack Dempsey pair, 6-7" wild Red Devil pair, 3-4" Firemouth pair, 3-4" Convict pair, 8" paratilapia polleni, 6" Green terror(f), 2x 4" pink convicts(both males) and a couple 5" stripped rapheal cats. All added at the same time.

The only real problem fish was the polleni, he was very territorial and ended up getting a beaten by the large dempsey or RD. Other changes were swapping male JD for another(same size), exchanged one pink convict male for female, added vieja bif @ 3", added 6x 2-3" jags, added 3x "petsmart" trimacs @ 2-3". Had male FM die(cause unknown). This tank stocking ran fine without any other incidents until I took it down 2 weeks ago.

I'd like to see some pictures of that.^ That sounds nice.:)

How about one of mine? :)

GT on the right is about 6" for reference.:headbang2
 
Another concideration with intentionally overstocked tanks is increased oxygination. Sumps help with this but powerheads to increase serface agitation should also be fairly high on the list.

first link is from back in July and the second link is much more recent. Most the stock, except 4 small jags and the female cons have been moved to a 180g tank(sorry no pics yet)

As an example, this is what I consider adequate in my case (You can see my stock in an earlier post). The tank is 190 US Gallons with a 50 US Gallons wet/dry sump. The main pump is a QuietOne 6000 (1,500 gph). In the tank, there are 2 Penguin 1140 powerheads (300 gph each), and a Magnum H.O.T. canister (250 gph) running the UV sterilizer. There's also an Emperor 400 (400 gph) just because I had it laying around. That's a theoretical 2,750 gph of water movement. Most of this is directed to the surface. The return line outlet for the main pump is near the surface as well giving even more surface agitation.

I also made an extra compartment in my sump that makes a short waterfall (and to put plants in) helping aeration. I don't do this, but you could also add an air pump and airstone in your sump.
 
Does lower temperature also lowers aggression???
 
Does lower temperature really lowers aggression???

Some people's theory is that if you keep the temperature lower, you slow down the fishes metabolism, making them more lethargic, in turn, makeing them less aggressive.

While this may accomplish what one would want, I don't believe it's best for the fishes. They will grow very slowly or be stunted. It very well may frustrate them (from being in less than ideal conditions) into more aggression.

I try to keep my tank between 80 degrees and 82 degrees. If the fishes could set the temperature on the heater, I feel this is what they would choose. At the end of the day, I try to do what's best for the fishes, not what's best for me (besides stocking too many fishes in a tank :D).

Also remember, warmer temperatures mean less oxygen content in the water. You have to make up for this somehow, either through more aeration (bubbles) or surface agitation.

mine is at 78F, seems alittle calmer than 82

78 degrees isn't that bad. But, you could take a look at other things that you can control and/or change that may accomplish the same goal to give them a better, more ideal temperature.:)

The bottom line is if 78 degrees works for you, good for you.;)
