Introduction to Clownfish
Introduction to Clownfish
Clown fish are known technically as Anemonefishes. Anemonefishes
are a subfamily of damselfish, in the pomacentridae family.
There are 26 unique species of 'Clownfish', 25 of them being in
the Amphiprion genus and only 1 in the Premnas genus. They are
typically a small fish, mature males only growing anywhere from
2 to 5 inches in length.
Habitat
Clownfish are only found in the tropical waters of the Indian or
Pacific oceans, and the Red sea. These climits provide a
suitable environment for enemonefishes due to their warm
temperatures. Clownfish tend to be bottom dwellers, and most
notably reside in inshore reefs, specifically inside sea
anemones. The anemone provides protection for the Clownfish both
by enabling the fish to hide, and with it's poisonus tenticles,
keeping other fish away. There is no definite information why
the Clownfish is not stung by the anemone, but many theories
exist.
Prey or Preditor?
In nature a clownfish will attract it's pray by swiming around
it's anemone and displaying it's bright colors. Once the victim,
all the time thinking that he is the preditor, begins to
aproach, the clownfish will recede into the anemone with his
prey following closely behind. The sea anemone once in contact
with the 'preditor' will sting, kill, and begin to eat the prey.
This leaves the leftovers for the Clownfish to snack on. Other
forms of food are planktonic crustaceans and algae that may
develope on coral or nearby rocks. Anomenes themselves may
provide food as the clownfish will pick at and consume dead
tenticles.
Captivity
This fish is a very good first choice for saltwater tanks, which
is one of the reasons they have become so popular in the united
states and parts of europe. Part of their suitability is found
with anemonefishes having a very small territory; which is good
for the small area offered in fish tanks. The substrate area of
tank, meaning the area on the bottom of your tank adjusted for
protruding rocks and sunken ships, is more important then the
total volume of the tank. A 20 gallon tank would be considered
the minimum recommended size for Clownfish. Living peaceably in
your fish tank a Clownfish would require aprox. 14 hours of
light and 10 hours of darness every day. These amounts may be
adjusted and are only suggestions. Be carefull of high nitrate
levels. Mature Clownfish can sometimes tollerate these levels,
but the larva and babies will almost certainly not. Include a
large variety of food when feeding Clownfish. Feedings should
include live brine shrimp, frozen food, algae and the
traditional flakes. Being that clownfish will have no preditors
in a fish tank a sea anomone is not requird to protect them.
Breeding
Many people believe anemonefishes will not breed without the
presence of a sea anemone, but this is not the case. After some
time, a particular spawning site will be chosen. This spawning
site will remain the same throughout the life of the Clownfish
pair. Clownfish will spawn all year round laying their eggs in
large batches. In the wild eggs are normally laid on coral or
rock that is near the anemone, though in your tank they may be
laid anywhere. Once laid by the female, the male clownfish
assumes the job of gaurding the eggs until they hatch, typically
4 or 5 days aftwards. When clownfish reach sexual maturity they
will strike out on their own, searching for a vacant sea
anomone. Clownfish may be expected to live around 3 to 5 years
in captivity.
