Luv4jjt--Cranberry has alot of hands-on experience from her recent work w/ this species, and is full of great advice and observations
Heres what i got on bearded ghouls-- maybe you'll find this helpful.
Choridactylus multibarbarbus
Common name: bearded ghoul, Many-barbed stingfish,
Maximum size: up to 6” inches
Minimum tank size: 25 gallons
Even though there are a four choridacylus species, only C. mulitbarbarbus is ever seen at the pet store. These fish are found in the Red Sea, Persian Gulf, Pakistan, India, the gulf of Thailand, and the Philippines. Apparently a tasty fish, choridactylus is sold in Asian markets as either fresh or dried salted. However, most specimens collected for the hobby come from the Philippines, where the fish is found inhabiting sandy or muddy bottoms.
Commentary: This fish is downright ugly or “cool” depending on your affections for the weird and unusual. The species color ranges from solid golds, to mottled browns and grays, to those highly prized specimens that are covered in pinks, reds, and coralline algae-like patches. The fins are frequently a different color than the body, and this species always has a dark band on the base of its tail. The head is rounded and insect-like and the eyes are set wide apart. Dangling from the lower jaw are multiple tassels or fringes giving the “bearded” moniker. Bearded ghouls are a very neat addition to a species only tank full of slow moving scorpionfish. I found them hardy, tolerant of tankmates, and good eaters, as long as the live foods kept coming. They fed only on live ghost shrimp, and refused or ignored guppies. They clumsily crawl over rockwork, so be aware if you keep this species with loose corals or have tenuously stacked rocks. I also observed they spent a good portion of their waking hours digging and partially burying themselves, so a sandy substrate is recommended. Lastly, I’ll reemphasize the point about their sting; choridactylus have rigid dorsal spines that can deliver a very potent sting, far greater than you’d expect from a fish this size.
Captive care
In the home aquarium bearded ghouls make an interesting and downright weird addition to a species-only tank. The three keys to success with this subfamily are a) sandy substrate, b) live ghost shrimp and 3) no food competition.
In this regards, ensure your tank bottom is composed of a few inches of sand or a finely crushed substrate, as these fish spend a lot of time partially buried. It’s not uncommon to see only the exposed eyes and mouth of a seagoblin, or a half buried head of the stingfish.

BTW- as you see from Cranberry-- she was able to wean her ghoul over to prepared foods, so its certainly something i would strive for
