I think you may have hit on a couple of key issues:

Varied diet
Larger tanks
More frequent feedings
More frequent water changes.

Fish? What are "Fish"?

I seldom grow up fish for sale, but I'm pretty good at getting fry to breeding size.

My observations but, as they say, your mileage may vary.

1) Frequent water changes - 50% weekly
2) Feed 2X a day. Higher protein foods work better, if the species can handle it
3) Use fresh food. If it is open and out more than a week, it isn't fresh. Keep food in the freezer and only take out what you can use.
4) Tetra Cichlid sticks (crush for fry) works well for me
5) Fish grow faster over sand/gravel than over bare bottom tanks
6) Fish grow faster in top tanks than in bottom tanks (stress?)
7) Fish grow faster with an appropriate dither (I like Rainbows)
8) Some light-- enough to grow algae-- seems to help. At least, you can see if they're growing . . .
9) Feed a variety of food . . . maybe a protein food in the morning and a veggie flake at night

I have also seen a difference of growth rates and I am at a loss as to why. It could be a water issue and/or a feeding issue. Some fish given to me have done very nicely and gained size and other seems to gain it more slowly. I have dropped fish off at the LFS which has the same water and their fish seem to seldom grow. They also seem to have a problem keeping inverts and yet I have them multiplying like crazy. If anyone has the solution about this, I am all ears!

What foods are you guys using?  I do not think it has to do with tank size because I have put fish into my 125 or 75's to raise them up and they do not grow as well.  I have also kept 6 1.5" fish in a 30 gallon by themselves and they do not grow well either.

Bigger tanks. I've found that once you get fish in 4 foot or longer tank-- especially 75G and up-- they grow a lot faster.

I had a bunch of Naevochromis trychogaster in a 40B with some other fish. I moved them to a 90G and I think they grew about 1/4" in the first ten days.

I do get better growth rates over sand than gravel. I think the fish are less stressed over sand as they get to sift through it all day and perhaps find a bit to eat.

Key to quick growth is clean water and big tanks. All my growout tanks are 55gal at least. I start with 10s and move them up to a 55.

That's strange.  My friend has that same problem.  I'd give him fish to breed for me and then I'd go and take some of the fry for me to raise.  Then I'd go to his place and the fry I took would be about twice the size of their brothers and sisters and all I do is feed them twice a day (aquadine-we feed the same food to our fish) and do a weekly water change of 25%.  Nothing special.

I having been having issues with the growth of my cichlids for some time now.  I have hit a point of frustration that I am planning on and have been selling almost all of my fish.  I have a fish room of around 1000 gallons (20+ tanks).  Each tank has at least one sponge filter and an aquaclear powerfilter on it.  My usual practices are 30-50% per tank weekly.  Tank sizes are 10-125 gallons.  I alternate feeding spirulina flake and NLS.  I generally feed one time a day on weekdays and twice a day on weekends.  Water here is very hard.  PH is generally 8.2+.  Tank tempertures range from 78-80.  I have had no problems with Nitrites or Ammonium.  I occasionally have Nitrates that get a little high.  Cleaning up the filters and water changes generally bring them back to very low levels. 

I recently had a guy who bought fish from me bring some back since he was tearing down his tank.  He lived relatively close and has a similar water supply.  He bought the fish(multiple species) from me about a year ago and they were 1-1.5 inches at the time.  They are now pretty much full grown 4-5inch fish that are actually bigger than my parents. 

I have ran an experiment with 2 30 gallon tanks and put 6 fish (1-1.5")in each tank.  In the last eight months I am lucky if I have gotten .75" for growth during that time.  So I do not think it is the number of fish I have in the tanks.

What do you think is my problem?  I am thinking there might be something in the water that is inhibiting growth. I am also thinking about changing foods (any suggestions on what you are using).  Any other suggestions or something I am over looking?
