乐生活Roa modesta is a common butterfly fish in northern Taiwan and Taiwan Strait. It inhabits 40-200 m deep sand-mud seabed, so it often appears in bottom trawl catch. According to the species caught, the species that inhabit the same habitat as the butterfly are usually catfish, grouper, grouper, thorn bream, stone. Bass and flounder, etc., are also typical fish on the sandy seabed. However, trawl fisheries of Pak Butterfly Fish are usually on the verge of extinction after being put into water. They have little value to use after they die, but a live fish is not cheap to sell in the aquarium market.
