mayan tailspot is big and in the centre, festae is small at the top... my mayan hasnt grown at all. i bought it at the same time as my dovii, both 1.5 inch, after a few months the dovii is now over 4 inch and the mayan 2 inch... maybe its jus mine!
I got both in my tank, I have small Mayan and a larger festae, Mayan has the large spot covering the tail and the festae has a small spot covering the top half but hasnt colored up yet.
