Polyp extension on an acro frag

[Fishko]

I got this frag for 5 dollars in a livesale. It was sold as a Aussie tricolor acro. Arrived today from wwc. I was just wondering what kind of polyp extentsion i should expect. My current params are 7.8 dkh 420 calc 1ppm nitrate .04ppm phos mag 1350, sal 1.026. I feed pretty heavy and my levels stay around there for nutrients. Here are current pics its been in the tank for about 2 hours. This is my first acro, i have a birdsnest which has taken off. And the rest of my lps is happy

Looks about right, you’re not going to see the same extension as a birdsnest.

Is my acro the same as a purple bonsai?
