I've been saying it all along. We always dismiss the notion that "fish will grow to the size of their tank" as being myth. But I believe it has some truth to it. Not to say you can keep an RTC in a 10g, but I do believe growth is stunted when fish are kept in small tank. Peacock bass are a perfect example. Look at the sizes of bass that are kept in 200-700g tanks. They're aren't even close to what you see in the wild. Now look at the 3ft monster fish that JohnPTC has in his 10,000g tank. THAT is how big they should get.
Think about it. Why is it that fish never grow to their full potential when kept in captivity? Because we keep them in 1-200g tanks, that's why, and they 'grow to the size of their tank'.
And you also see this a lot with koi. Koi kept in massive ponds can reach 36" in no time. We have koi in a pond that's about 2000g, and have had some for over 8 years, and are barely over 24".
