Prostrata Vs. Millie

They look really close to me, how do you tell them a part and why were at it might as well show some off. Lets see them.

I tht prostratas have shorter branches. I'm sure there is more to it that than. But just sayin'

Could we get some comparison pics?

Mr. Microscope · Apr 29, 2013

I think Prostratas have a rounder appearance to the tips. I could be wrong though.

ParkerB · Apr 29, 2013

From my experience prostratas branch more and milles table more. I could have them backwards.

I always thought that prostratas had more of a pointed tip. But I very much so could be backwards. I also thought milles have a little more of a thicker branch like a Hyacinthus

milles are stubbier and have more radial coralittes. prostratas are much smoother and elongated. sometimes you wont be able to tell as small frags or mini colonies

ooops, i meant incipient rather than radial.

Anyone have colony pics of both in their tank. All my prostrata's are just frags.

Well now I'm really confused. My so called Millis look a lot more like prostratas than millis. Does anyone know for sure if Rose Millis and Palmer's Blue Millis are actually Millis? I heard from one member (ParkerB), that he heard the Palmers Blue was actually a Prostrata.

The corallites are identicle, the differentce is in the growth and colony structure. You can't tell frags apart.

Acropora millepora described by Vernon-
"Colonies are corymbose cushions, with short uniform branches. Axial corallites are distinctive; they are tubular in shape. Radial corallites are closely compacted and all the same size. They have prominent lower lips giving a scale-like appearance."

Acropora prostata described by Vernon-
"Colonies form corymbose or irregular cushions with thin elongate branches. Axial corallites are tubular in shape. Radial corallites are all the same size. They have prominent lower lips giving a scale-like appearance."

Here is a Scripps A. millepora i have;

And here is a Pink A. prostrata and a green one.
