Cory Sterbai Growth Rate

[AeonMapa]

Hi I was planning to get a group of 6-8 of these little guys and I was wondering if anyone knows their rowth rates? I've seen adults nearing 3 inches but the stores  mostly sell 1/2 specimens

Since you don't seem to have any luck getting a reply, I'll chime in.
 
No expert on Sterbai whatsoever, but I got mine at approximately an inch 14 months ago, and they all are +/- 2inch now.  The largest female is perhaps a tiny bit over 2 inch.
So, in case you needed them to grow to max size fast, nope they don't... 
 
From what I've heard cories grow pretty fast the first 3-4 months and then they slow down.  Also, from what I can find on the net they(Sterbai) generally don't grow to 3inch(or over).  Those are probably misidentified Corydoras Haraldschultzi.
