Catfish are common fish found in freshwater
aquariums. Catfish are very unique and differ from other fish in regards to
their health and care. The most distinguishing feature of a catfish is the
prominent "barbells", which look like whiskers on a cat, hence giving these one
of a kind fish their name. The other thing that set catfish apart from any other
fish is the fact that they have no scales. They also possess a strong, hollow
ray on their fins that a stinging protein can be emitted from if the fish is
irritated or in danger.
The most common catfish found in aquariums are the armoured catfish. This group
is smaller in size than other types of catfish and make a great addition to an
aquarium. When you are setting up your tank initially, it is best to decide then
whether you are going to house catfish. Your decision will impact the type of
gravel or sand you will use as well as the pH of the water within the tank.
Armoured catfish prefer soft bottom material because they forage for food within
the substrate. Catfish feel more secure when they are hidden from the light, so
be sure to have caves and hiding places for this type of fish.
Overall, the care of catfish does not vary from caring for your other fish. You
should try to include a food that will settle on the bottom of the tank as these
fish are bottom feeders. The water should have a temperature in the middle to
upper seventies and the pH should be neutral. This is usually the same set up
and water balance you will use to house other fish as well, so it should not be
a major concern when you add your catfish.
Catfish are known to be somewhat goofy and comical, but this may depend on the
species of catfish you have. Their behaviour will vary, but as a whole, the
catfish is an entertaining addition to an aquarium. There are group and
schooling catfish that get along well with each other. There are also loners who
always stay away from their neighbours. Catfishes are the ideal candidates for
community tanks because they inhabit niches and shelters on the bottom not
occupied by other aquarium inhabitants. They generally get along well with all
types of fish. Only in combination with some larger Cichlids can there be a
problem as the Cichlids tend to extend their territorial claim to the entire
tank.
The one thing to consider before adding a catfish
to your existing aquarium set-up is the size of the other fish. While catfish
generally get along with most fish, they are a predator and will attack and feed
on smaller fish. Catfish are also nocturnal, and should be fed later in the day
or at night. You may have to adjust the feeding times depending on what your
schedule is now and what other types of fish inhabit the tank. With the number
of species of Armoured catfish, you will be sure to have a colourful and amusing
aquarium with the addition of these comical fish. As with all fish, be sure to
keep the aquarium clean and healthy so as to ensure the health of the fish as
well as your enjoyment for years to come.
