Cramped Acanthophyllia = issue?

[Ryebreadiest]

I’m looking at picking up a beautiful and huge Acanthophylia as a centerpiece, but it will only be able to inflate to about 6”x8” in the spot I have picked out while it seems to be nearly 10”x10” when given infinite room. Is this a problem long term? Should I look for a smaller one?

I'd pass an look for a smaller one, but have not dealt with this situation myself with an acantho. Following.
