We used to sell Clown Knife Fish in the aquarium store I used to work in as a teenager. Cool fish. Lots of aquarium fish have escaped into Florida and become established, including Oscars, Peacock Bass, various catfish and now, apparently the Clown Knife Fish. They are edible, at least to Thai's:
The clown featherback is commonly seen in the cuisine of Thailand and other southeast Asian countries. In Thailand when deep-fried as Pla krai thot krathiam (ปลากรายทอดกระเทียม) it is served with a spicy dipping sauce on the side made by mashing up coriander roots, bird's eye chillies and garlic, and mixing this with fish sauce, lime juice and sugar. The clown featherback is also the main fish used in the production of fish balls.
