The Wolf Fish has
a dangerous appearance and rightly so. This is an efficient and
ruthless predator. The body will be dark gray or brown with a
darker horizontal line that disappears with age. The belly will
be white. The jaw is blunt and pronounced with very sharp teeth.
The body is long and round.
The most important part of your aquarium when considering
purchasing this fish is a solid, tight-fitting, and heavy top.
They are
extremely powerful and capable of breathing out of water.
While large, very aggressive fish may stay alive with this
predator
it is wise to keep them by themselves. They grow very quickly
and need a large tank from the beginning. The aquarium size
as listed in the facts is merely a starting point (for a juvenile).
Upgrades will be necessary, in excess of 100 gallons. Rocks
and
plants will provide appropriate hiding places. There should
definitely be dark areas in the tank or dimmed lighting as
the Wolf Fish
is nocturnal. Bright lights may stress it out or increase
aggression. Care should be taken when cleaning the aquarium
but human contact
is usually avoided. Small fish are not tankmates, they are
meals. These fish are very hardy and forgiving when referring
to water
conditions. Use strong filtration and weekly water changes
to clean up the mess these fish make, especially after feeding.
This fish will eat anything that can fit in their mouths
and may still kill fish that they cannot fit in their mouths.
Don't give them the opportunity to eat your other fish. Carnivorous
foods are obviously required. Large foods like feeders, fresh
meat, and chunks of beefheart are appropriate.
Breeding is all but impossible in the home aquarium, except
for extremely large aquariums. It has been reported that
they have been breed in ponds and public aquariums.
Sexing is unknown.
