Wolf eels are referred to by various names in different countries. Some of the different names for wolf eels are listed below:

  • Wolf eel
  • Carpet conger
  • Eel Blenny
  • Greenling
  • Giant Wolf eel
  • Eared eel
  • Mud Blenny
  • Seawolf

Weight and Size

The weight and size of a wolf’s eel depend on various factors such as diet, age, water conditions, and environmental factors. Typically, adult wolf eels measure between 1.5 feet to 2 feet (18 to 24 inches) in length and weigh between 5 to 10 kilograms. 

It’s important to note that there are different categories and species of green eels distributed worldwide. There are approximately 800 different species of eels belonging to various families and genera.

Lifespan and Reproduction

The wolf eel is a stunning species, and its lifespan varies depending on factors such as proper care and environmental conditions. In the wild, wolf eels have a longer lifespan compared to many other fish species, living up to 22 to 25 years. In captivity, they typically live slightly shorter lives, ranging from 18 to 20 years.

The reproductive process of wolf eels is unique. These species reach sexual maturity at around 5 to 6 years of age. During the winter spawning season, male and female eels engage in courtship rituals to pair up for spawning. 

The female eel releases her eggs, which can number up to 10,000 at a time. The male eel then fertilizes these eggs externally. The male eel guards the eggs until they hatch, which typically takes 3 to 4 weeks. After hatching, the larvae enter a larval stage, beginning the next phase of their development.

Aquarium Care Guide for Wolf Eels

The green wolf eel is a saltwater species. If you’re considering keeping a wolf eel in captivity, there are several essential tips to keep in mind. Let’s explore some key considerations for successfully caring for wolf eels in captivity.

Tank Size

Green wolf eels are sizable creatures and require a spacious tank. The minimum tank size recommended for wolf eels is 100 gallons, as these species need ample space for swimming and exploring. If you plan to house other tank mates with your eel, larger tank sizes are preferable.

Tank Decor for Eels

Tank decoration is crucial for creating the ideal environment for wolffish. Craft a natural habitat by using fine sand as a substrate to mimic their natural surroundings. Avoid sharp substrates that may cause injury. Incorporate live rocks to provide hiding spots and create a more naturalistic environment. Additionally, consider adding artificial plants to further enhance the resemblance to their wild habitat.

Water Parameters

Cool and oxygenated water is essential for the well-being of wolf eels. Regular water testing is crucial to maintain optimal conditions, with water temperatures ideally between 60 to 70°F and a pH level ranging from 7.9 to 8.4. It’s important to create water movement in the tank to ensure adequate oxygenation.

Performing regular water changes of 15% to 25% every 2 weeks is recommended to remove impurities and maintain water quality. Additionally, clean the aquarium glass regularly and ensure proper water flow to prevent the buildup of debris.

Tank Mates

While green wolf eels can be territorial and aggressive, especially towards other eels, selecting tank mates carefully is essential. Choose non-aggressive and calm species to coexist peacefully with wolf eels. Below are some suitable tank mates to consider:

Diet for Eels

Eels are carnivorous species that require a proper diet. A varied diet for wolf eels should consist of meaty foods such as:

Diet
  • Shrimp
  • Squid
  • Crabs
  • Crustaceans
  • Frozen foods
  • Snails
  • Small fishes
  • Invertebrates

Maintain a consistent feeding schedule and avoid overfeeding. Feed adult eels 2 to 3 times per week. Adjust the feeding amount based on the size of the eels to ensure they receive adequate nutrition.

Common Disease for Wolf Eels

Green wolf eels are hardy creatures but, like other fish, they are susceptible to common diseases. Below are some of the most common diseases that may affect green wolf eels:

Disease Names
  • Ich (White spots)
