Maybe thats the case in some cases, but not this one, the shop in question is run by father and son, the RTC is their pet, they dote on it.
Their tanks are the cleanest I have ever seen, they are incredibly responsible selling fish to people who know what theyre doing etc.
They are expensive no doubt, but the quality is second to none.
They have a massive indoor pond he could happily go in, but is fine where he is in the tank, he just stopped growing, he grew really quick up to 10" then just stopped, then grew VERY slowly over the last 10 or more years I have been going to the size he is now.
Fish are like people I think, some grow very tall and big, some stay very short, my best friend called diddy is just over 5 foot in well over 6 foot.
Dont think fish are much different, not all carp grow into monsters either
