The Sea Goblin (Inimicus didactylus) is a type of scorpion fish that can be found among the Indo-Pacific Ocean. They have brown and beige colors, relying on camouflage to ambush prey. It can be difficult to train a Sea Goblin to eat frozen food, so live food (shrimp and minnows) should be on hand at all times. They reach a maximum size of 8 inches, but due to their sedentary habits, do not require a tank over 40 gallons. They will ambush smaller invertebrates or fish, so it is recommended they be kept with fish of similar size. The dorsal barbs are venomous, so use caution when hands are in the aquarium.
