extremely slow growing fish. I have had my two big ones since 2005 and they have probably only grown an extra inch since then. I got another two in 2006, they were probably an inch long then, they are now around 4 inches. I dread to think how long they take to reach 12 inches, probably about 25 years

mind you, some say they can live for 50, even 80 years. Mind you, Masheer can live for over 100 years so I don't see why CL can't be the same?
I should add that these fish are extremely social and
must be kept in groups. They don't like being on their own in a tank, it can stress them a lot. Mine are always together as you can see
