If someone is going to take the time to sneak a coral in from restricted waters I don't think they are not going to sell it for the price of a lobo. Acan Maximas are pretty dull & drab in color It would be highly unlikely anyone would go out of the way to collect one unless it was specified.
Distinguishing Characteristics
Like the starry cup coral, heavy septal spines are the dominant characteristic of this species. However, the diameters of its calyces are much larger, up to 5 cm, and polyps may expand to twice this diameter. This species is endemic to Oman, meaning that it has been encountered in only Oman waters, having been described from a specimen first found off Ras al Hamra.
Habitat
Thus far, fleshy artichoke coral is very uncommon and has only been collected from the ridge area lying between Ras al Hamra and Al Fahl Island in the Muscat area, and in the nearshore waters at Sahd, Dhofar. It appears to be favored by relatively low light and high turbidity conditions that are present over sandy bottoms where most other coral species are not abundant.
