It is around .75" and is the only one with that coloration. It has the same barring pattern that the others have but a lot of fry having barring like this at this size.
Looks nothing like the Festae I got at an inch..the bars we're evident at the 1inch size including the Y pattern. The spot on the back fin was also evident. Might just be the angle of the picture I'm seeing also.
You are right. I got a hold of the festae breeder and he said the tank used to have some red zebra fry in it, so he must have netted one of those when he was grabbing the festae.
