I'd probably be a bit more optimistic, quantitatively by 3"-6" on average, but it appears to me the gender matters, not to mention the genetics. If my thinking is correct, as laid out in our RTC thread, the females grow the biggest and/or the fastest and should be 3'+ after 5 years or some such, ~4' after 10-15 years. But all in all, I don't expect 5' or 6' cited by those naysayers who know a few things about an RTC but not enough in depth, IMHO.Everyone seems to forget even large fish take many yrs to get that way even in the wild... not many people actually have regular RTC's over 30" either. The hype and scare tactics spread by the masses who have never even owned any of these fish is ridiculous. Any rtc white or reg colored will attain 20-24" in the 1st 2 years. After that growth slows down alot. Ive had reg. rtc's 5-8yrs old that were still only 28" and kept in 12'diamater swimming pools. 36"+ rtc would be 10-15 yrs old. Im surethebiggerthebetter can attest to this aswell. Largest rtc ive seen in person came from ted himself A Anythingfish and it was only 38" on the tape. 2 many people exaggerate sizes. Vince is about to leave the country for a bit also.... u prob wont get a response as most his fish just traveled across the u.s. to a new home....
My first golden/platinum rtc is 5.5 years old and about 30 inches. The biggest golden/platinum rtc I am keeping is a bit over 34 inches and around 5 years old. All of these came under my care when they were 3-6 inches. The growth is typical compared to normal rtc. 20-24 inches in year 1 and up to 30 inches by year 3-4... then much much slower. I've been told by keepers in Asia that the golden/platinum version won't grow pass the 24 inch mark but this is entirely false!vincentwugwg ?? Your move, bro. Your expertise is needed.
