What directly translates the limited range and deep habitat into scarcity in the marine aquarium trade?

Answer

Difficulty and cost associated with operating safely at depths approaching 100 meters for collection.

The scarcity of *Chaetodon daedalma* in the aquarium trade is a direct function of its natural environment. Collecting fish near the surface (like the 10 meter range) is manageable, but operating safely and effectively at depths approaching 100 meters introduces significant logistical challenges, increased risk, and higher operational costs. This difficulty in accessing and collecting specimens from their primary habitat inherently limits the supply that can enter the market, which consequently drives up the market value for any specimens that are successfully acquired.
