"Delicious!"

Sorry... I don't know, but couldn't help myself. Did you buy it, or are you thinking of buying it?

I’m thinking about it but I’m worried it’s a Juvenile wolf eel.

It look like Scarlet Frogfish.They require high water quality, are saltwater fish, and are not suitable for beginners. They also have a predatory nature towards other small fish, so extra care is needed when keeping them with other fish.

Ooh, that's a new one for me - Warty Prowfish, Aetapcus maculatus (it does look remarkably like a frogfish of some kind, but it's slightly too elongated and it's dorsal fin runs all the way up its head).

It's technically a scorpionfish, but it lacks the venomous sting (it does, however, sometimes release "a cloud of noxious liquid" when startled; at the moment, I have no idea if the liquid is harmful in anyway or just distasteful for predators).

A temperate water (preferred temps of 15-20.2 C or 59-68.4 F) ambush predator that feeds mostly on crustaceans and which prefers sponge/macroalgae habitats. They reportedly shed their skins.

The site below has a little more info, but it also has a specimen similar in color to yours in their species image gallery (these reportedly get to 22 cm/8.7 in:
