What type of Acan is this?

Just purchased these guys the other day. I really like the colors displayed, I was wondering if anyone knew what kind of Acans they are.

Looks just like a standard rainbow. Doesn't appear to be any special named variety.

agreed.

i personally wouldn't even consider it a "rainbow" acan. i see just 2 colors.

Micromussa lordhowensis

Those are micro lords, not true acans. True acans are called echinatas by the hobby. There is also a species of acan called acanthastrea pachysepta that looks like a lobophyllia.
