Why are scolys more expensive than acanthos

[Mr. Acantho]

They're both pricey corals, but scolys tend to be more expensive. However, they tend to be smaller than scolys so I'm trying to better understand the general price difference.

They aren’t in my experience. Scolys in the 300-400 and acanthos 600-900. Then the striking ones scoly: 1k, acanthos 2.5-5k
