Well I got my 6 around the exact same size and time (February 2020),
and mine are only around 3 to 3.5".
So compared to mine yours are growing like weeds lol
Where did you get yours from?
Well one is about 4.5 inches the rest seem to be near 4.


I special ordered mine from an LFS.

Mine are growing super slowly but may be due to diet honestly. I feed pellets and flakes and these guys always take the flakes 10/10 over pellets which is frustrating.
