I didn't sell it to you did I? I couldn't have., you must have bought it from someone else who stole it from me!!! now got me thinking, I had a few one time and sold some...but 
as for the size issue, bigger is better or is it? check out my latest theory!

New theory!
I've kept some specimens in freshwater for many years, even in slightly acidic water, no ill effect, but the fish remained smaller, around 7" for 4 years.
Some may say its cruel, or unhealthy, but I beg to differ with the following supporting evidence.
Scats are found in land locked lakes in Phillipines, never connected to the ocean.
Trouts/Salmon/Chars-that sea run, anadromous grow much later, previously believed due to the abundance of food, but is it? I've seen that many fish, when kept in brackish conditions grow much faster and larger. the landlocked specimens breed and live healthy just like the saline counterparts.
Monodactylus sp,. will not grow very large in pure freshwater, but the ones in the ocean reach over 12" in lenght!!! Same with scats, the ones caught in the ocean grow much larger, and the ones in freshwater take much longer to grow. Most people have not even seen full grown mono argenteus, they're like a dinner plate.
My epinephelus lanceolatus grouper reached 16" in a hurry, and has maintained that size for the past few months, still aggressive as ever, and eats, but not much more growth.
I will turn over the theory of certain fish "needing" salt as they grow old, its a old theory that has not scientific support, its a theory at best
The theoriy is that the mineral content in the salt water that promotes the rapid grown, increased calcium, etc...
This is not just a hunch, I have pages of evidence to support this theory, but it has not been mentioned to my knowledge
