How fast do calvus grow? How long would it take for a 1-2" to reach 5"

I'm under the impression that 5-6" will take a couple of years or more.

I've heard it being as slow as "an inch a year".

under high protein and very good water conditions, mine have grown from 1.25 inches to 2.25 inches in one year.. so yeah, you're looking at about an inch a year..
