Datasheet

General Description

The Wolf Eel, scientifically known as Congrogadus subducens, is often mistaken for a Blenny but is classified as a pseudochromid, specifically a Dottyback. It is also known by various other common names such as Carpet Eel Blenny, Eared Eel Blenny, and Green Wolf Eel. This species showcases a body coloration of brown with hints of green throughout.

Aquarium Suitability

The Wolf Eel thrives in aquariums with a capacity of at least 125 gallons, providing ample hiding spots within the tank. It's crucial to have a securely fitting lid on the aquarium to prevent the eel from escaping. While it can coexist in a reef setup, caution is advised as it may prey on smaller fish and crustaceans.

Care and Hardiness

Categorized as an easy-to-care-for species, the Wolf Eel is relatively undemanding when it comes to its care requirements. It adapts well to captive environments and is known to be hardy, making it suitable for aquarists of varying experience levels.

Reef Suitability

When considering integrating a Wolf Eel into a reef aquarium, it is important to exercise caution due to its aggressive temperament. While it can exist within a reef setting, potential risks to smaller tank mates exist, particularly fish and crustaceans.

Aquarium Setup

Creating an ideal environment for a Wolf Eel involves setting up a tank with a capacity of 125 gallons or more, along with numerous hiding spots. A secure lid is essential to prevent any escape attempts by the eel. Maintaining water conditions with a pH level of 8.1-8.4, a specific gravity of 1.020-1.025, and a carbonate hardness (KH) of 8-12 is recommended for optimal health.

Behaviour

Wolf Eels are classified as aggressive in temperament, which can influence their interactions within a community tank. Due to their predatory nature, they may display territorial behavior and should be carefully monitored when housed with other tank mates.

Feeding and Diet

Being carnivorous in nature, the Wolf Eel thrives on a diet rich in meaty foods. Their feeding regimen should include small marine fish, chopped clam, and prawns to ensure a well-rounded nutritional intake that supports their overall health and vitality.

Dimorphism

For the Wolf Eel, differences in physical characteristics between males and females, known as dimorphism, may exist, though specific distinctions are not detailed within the available information.

Habitat and Distribution

In their natural habitat, Wolf Eels can be found in various regions, typically residing in rocky crevices and caves along the ocean floor. They are native to specific areas but can adapt to aquarium life with proper care and a suitable environment.
