Two accros to identify and sourcing?

[Guillaume]

Hi all,

These are two accros, the green I got since 1 1/2 year and the other since 9 months. The green don't have any rings (not the right word I know) around the polyps. I guess we cannot narrow the location they come more precise than the large "Indo-pacific region"?
Thanks !!

First one just looks like a loose growing green Milli http://sdmas.com/corals/47.php. If you wanted it to grow more in a tight form give it some more water flow.

Second Desalwii http://sdmas.com/corals/679.php.

Thanks Jason. You seem to be doing a great job here.
The green is right one feet from my MP40 blowing up to 90%. It developped even black mucus (infection I guess) on a branch and this branch growing flat on the flow side.
Maybe a more general exposure to all the coral to the flow, so less close to the pump may help grow it tighter.
What you think?
Tx!

After looking at the library, I'm not sure it is a millepora. The radial coralite walls or lips are much smaller than millepora, even almost innexistent.
Any idea of one accro with no or almost no radial coralite walls to orient my search?
Thanks!!

Looks like a tenius to me

I noticed this too. The growth form and corallite structure do not line up with A. millepora.

Keep in mind that in captivity, corals can take on very different morphologies than their wild counterparts. This is especially apparent with the radial corallites of Acropora spp.

That said, I think your first coral has a more upright growth form. A. abrolhosensis or one of the other species showing an arborescent growth form could be a possibility. That is no more than a guess though.
Here's a wild one that was recently up on LA DD.

Mmm, interesting. Nice site you provided.
I will need to continue searching. The list is long, so the search is.
Thanks for your input !

i had this coral in the past, reminds me of abrolhosensis

Interesting, the axial coralite is quite the same and branching patern too. Maybe my specimen doesn't develop outward going radial coralite in aquarium...
Thanks for your comment.

I also used to have an acro that looked very similar and for some reason never developed any substantial radial corallites. I wasn't able to ID it with any level of certainty, but A. abrolhosensis was the closest I could get.

Like you said, the search is long. Don't stop hunting, because it's easy to overlook a species.

Thanks Klepto.
I just realised a few minutes ago that a new growing head that is out of the flow is developing more extended radial coralites...
