The maximum potential size is a freak of nature as far as I understand. Take a look at Robert Wadlow, world's tallest documented person to live.

8'11" and still growing when he died, one could say that is the maximum height for humans, will any of us reach it? No. I would say in my personal opinion that you should take those "max sizes" and accept that not every fish is going to hit that in some species. However my opinion is just that, an opinion.
Maybe I could word my post better, but yea I don't mean to max fish to their species potential size, more like maxing each fish to its fullest potential. It's like we somewhat frequently see silver arowanas that reach 1.2m in wild life documentaries but we rarely see one reaching 1m in the home aquarium hobby, there must be a reason that home aquarium fish are smaller in average(or some one can point out to me that they actually aren't) and I was wondering how we as aquarium hobbyists give them a little boost and let them reach full potential.The maximum potential size is a freak of nature as far as I understand.

Yes I totally agree, the sense of pride of having such a big fish and I also believe that size reflects health too which is also something worth being proud of.There’s no exact formula, but I’m always looking into this as well because for me I find a great sense of pride in rearing a fish to its maximum potential. My oversimplified ideals that I try to follow are,
Firstly, totally unproven but I believe how a fish is handled as a fry can set the whole tone for its life. In the first year they will be growing more rapidly than ever again. Any growth lost from long shipments, stress, weaning of food, all comes off the top of the final max size at the end in my opinion.
As for what should be provided:
An aquarium far beyond the minimum size for a species. A steady source of high quality foods that fill all nutrient requirements (I’ve read multiple smaller meals over a day as opposed to one large is better for consistency in growth). Depending on species, a level of current to assist in metabolism. Very clean water, or as clean as economically possible. A lack of chemicals that may damage cells, cellular growth, or replacement. Lack of competition.
these are just my educated guesses but they all have some evidence of truth from everyone’s experiences in the hobby
