ID this Acan ?

[All Delight]

I got these a couple of weeks ago. They seem very different from other acans that I have.

The polyps get very "puffy" and are pretty big. About the size of a 50 cent piece. And the texture of the polyps look smooth.

Acan Lord, non-indo. I have an indo colony that each polyp gets the size of a fifty cent piece and constantly has all there sweeper tenicals out. Nice Pick Up.

Is there a piece of the skeleton showing?
Thought it looked like some kind of favia

 

[Bcollins111900]

Def. not favia

 

[All Delight]

Yah not Favia. I'll take a picture when the polyps are not open.

 

[Marcio]

Actually not favia. IMO looks like blastomussa welsi.

 

[Bcollins111900]

Def. not blasto welsi

 

[All Delight]

Yah, not Blasto either.

It's an Acanthastrea sp., but never seen anything like it.

Are the polyps joined or connected?

 

[Underwaterparadise]

looks like a really puffed up lord

I think one type of acan has polyps that grow bigger than normal. I can't remember the name, I will try to track it down.

Try and get it to deflate and take a pic.

is it acanthastrea maxima? those polyps are bigger then normal lords.

Without the skeleton in your hand under a microscope and the knowledge to differentiate between genus down to a specie level, I would definately say nothing is for certain nor definate about this coral. The more I do look at all the various species including acanthastrea as far as appearance it does indeed look almost spot on to a few favia like this for example:

also check the middle upper pic of this one :

Ya never know, but I do know it's plump and pretty ! Thanks for sharing.

Nope.


I agree no way to tell for sure without skeletel structure but I still say Lord. I have a lord at home with polyps that expand to the size of a silver dollar or larger!

This looks just like one of the two corals I rescued from an LFS about 3 years ago. This was before the big acan craze and I was told then it was a favia. I was suspicious it was something else because I had never seen a favia like this (not too many people knew what an acan was back then including myself). The coral ate like a pig and did recover and colored up more and became more puffy just like the pic at the beginning of the thread. I wound up trading it so I cannot take any more pics. Here are the pics I took when I rescued it and you might be able to make out the skeleton. These were full tank shots so I'm not able to blow the pics up any more than they already are.
