Care For Arowana
Water Condition/Water Change/Feeding
Arowana is not a difficult fish to keep. After all, it has survived throught
millions of years until man came into its way. All you need is to spend one
to two hours per week taking care of it and you will have years of enjoyment
watching this beautiful fossil dragon swimming in your aquarium.
Water Condition
pH: Althought arowana can withstand a reasonable range of pH, they should be
kept in water that is slightly acidic or neutral. Make sure you check you pH
regularly, especially if you have something in your setup that will altered
pH, eg peat, CO2 system(in planted aquarium), etc.
Temperature:Water temperature should be maintianed at between
26C-30C(79F-86F). Avoid sudden change of temperature as it may chock the
fish can cause problem like tail dropping. Although arowana can withstand
higher temperature, this is not recommanded especially if it is for long
period of time. High temperature cause wrinkling of the gill cove and
destroy the authentic look of the fish.
Hardness: Arowana like soft water but can also tolerate water with
reasonable hardness.
Water Change
Arowana is carnivorous fish. they produce large amount of waste. High
amonia, nitrite and nitrate are common problem in arowana tank. Regular
water change is the easiest way to deal with it. 1/4-1/3 water change per
week is recommanded, 20% twice a week is even better if you have the time.
Make sure you adjust the temp and pH of the new water similar to the tank's.
Sudden drop of temperature or pH is dangerous and could sometime proved to
be lethal.
Feeding
Small arowana(below 15cm> should be fed three times a day, medium
arowana<15-35cm) twice a day and large arowana(above 35cm) once a day or
alternate day. Variety in food is important to avoid nutritional deficiency.
High fat food like feeder fish should only be used sparingly to avoid drop
eye problem. If arowana is overfed for a long period of time, it may lost
its appetite and starve itself for a periods of a few days. Overfeeding can
also shorten the lifespan of arowana and affect its breeding capability.
Food for Arowana
Insects/Fishes/Crustaceans/Worms/Amphibians/Pellets & Sticks Food
Introduction
Arowana is a carnivorous fish. In wild, its food consist mainly insects,
fishes, prawns, worms and small amphibians. Live food are preferred by
arowana though they can be trained to accept other food. Variety in food is
a MUST to avoid nutritional deficiency.
Small arowana(below 15cm> should be fed three times a day, medium
arowana<15-35cm) twice a day and large arowana(above 35cm) once a day or
alternate day. High fat food like feeder fish should only be used sparingly
to avoid drop eye problem. If arowana is overfed for a long period of time,
it may lost its appetite and starve itself for a periods of a few days.
Overfeeding can also shorten the lifespan of arowana and affect its breeding
capability.
Live food is generally more nutritious then its counterpart. However, the
risk of introducing disease into the tank is increased when live food is
used. This is especially true when the live food is waterborn(live in
water). Live food should be quaranteen for at least a few days before
feeding to the arowana. If you have doubt in certain food, the golden rule
is "If in Doubt, Don't Use It". There is always other types of food
available.
Insects
Crickets:
Crickets are nutritious food for arowana. The risk of disease transmission
is very low. Use the appropriate size crickets for different size arowanas.
Hard shell of crickets should be removed when feed to baby arowana to avoid
intestinal injury. Use only farmraise crickets as wild caught crickets may
be contaminated with insecticide. You may feed the crickets vitamine A rice
food like carrot before feeding it to arowana. This is a good way to
transfer nutrient. Vitamin A enhance color of arowana(esp red). Crickets may
be frozen to avoid hassle, the percentage of nutrients retained when frozen
is uncertain and require further study.
Cockroach:
Similar to cricket. Do not feed dead crocroach to arowana as it might have
been killed by insecticide. It is advisable to keep the crocroach for a
couple of days before using it, any insecticide contaminated crocroach would
be death by then.
Centipedes:
Centipedes are very nutritious food for arowana. They are commonly used in
Asia to enhance and intensify the color of arowana. Unfortunately the
availability of this food is low. Frozen centipedes are more readily
available then live one.
Fishes
Live Fishes:
Almost any bite size fish that is not poisonous can be arowana's food.
Feeder gold, meadow, baby koi, baby catfish and small chidlid are commonly
used. There is pontential risk of disease transmission when this type of
food is used. Quaranteen is a MUST as it will screen out most(but not all)
sick fishes. To transfer nutrient or medication to arowana, you may feed
them to feeder fish right before using it. Some fishes, like goldfish are
rich in fat and will precipitate drop eye problem. Use them sparingly.
Goldfish is also believed to contained enzymes that will lead to nutritional
deficiency in arowana, use it sparingly or avoid using it.
Fish Meat:
Fresh fish meat can be used. Trim all the fat away and cut them to bite
size, wash them before use to avoid contamination of the water. Avoid frozen
fish meat as denatured protein may lead to liver and internal organ sickness
in long run.
Crustaceans
Live Prawns/shrimps:
Prawns/shrimps are rich in vitamin A which enhance arowana's color. They are
very nutritious food. Avoid feeding baby arowana shrimps as thier shells are
hard to digest and may cause intestinal injury. Do not leave live
prawns/shrimps in arowana tank as they encourage arowana to search downward
constantly for them and hence may precipitate drop eye. Once again, there is
also a potential risk of disease transmission.
Prawn Meat:
Use only fresh prawns. Avoid frozen prawns unless you are very sure of its
freshness as denatured protein may lead to liver and internal problems in
long term. Removal of head is recommand as it is hard to digest and also the
gill may have high concentration of germs/toxin. Prepare the prawn in bite
sizes and wash it before use.
Krill:
Krill is a nutritious food and it is readily available. Use appropriate size
krill for diferrent size arowana. Crush the shell then soak the krill to
soften the shell proir to feeding baby arowana as hard krill may cause
intestinal injury.
Worms
Bloodworms:
Bloodworms are mainly used to feed baby arowana. They a nutritious food.
Rinse away impurities before use. Do not feed it when frozen as it may cause
intestinal upset. Avoid old age bloodworms as it is hard for baby arowana to
digest. Live bloodworms is preferrable but commercially available bloodworms
are equally good when fresh. Freeze dry bloodworms may also used.
Tubifex Worms:
Tubifex worms are collected in highly contaminated drain and should be avoid
unless properly treated. Commercially breed tubifex worms claim to be
cleaner but its source are sometime questionable. Remember the golden rule:
"If in Doubt, Don't Use It". This goes to frozen tubifex worms too. Freeze
dry tubifex worms are cleaner but possibility of germs survived through very
low temperature cannot be ruled out. High heavy metal content in the source
is also a worry.
Mealworms:
Mealworms are healthy and nutritious. Avoid feeding them to baby arowana as
thier hard shell is difficult to digest and may cause digestive problem
or/and intestinal injury. Use worms that have just shed its shell. Darker
color mean older shell. So choose pale looking mealworm. Drowning the worm
proir to feeding is recomanded if the fish accept dead worm. Head can be
removed to minimise digestive problem.
Earthworms:
Earthworms are very healthy and nutritious. Risk of disease transmission is
minimal. Squeezing the soil out before feeding is recommanded. Or better
still, feed the earthworm with nutritious food to clear the soil and
transfer the nutrient. This is a highly recommanded food by most aquarist.
Pellets/sticks Food
There are many commercail pellets/sticks food available. Their nutritious
value varies. Choose reputable brand. Pellets/sticks food specially
formulated for arowana is recommanded. However, this should not be the only
food of arowana.
Amphibians
Frogs:
Frogs are very nutritious food for arowana and are commonly used in Asia.
You should be certain that the frogs are not poisonous before feeding them
to arowana. Frogs should be quaranteen for a few days before use as they are
often collected in Padi(padi)field where insecticide is frequently used. Do
not feed death frog to arowana. Frogs are believed to enhance arowana's
color.
Lizard/Gecko:
Lizards and geckos are also very nutritious food for arowana and are often
loved by the fish. They are usually not commercially available or demand a
very high price. Geckos is found in almost every house in tropical region.
Catching them is hard work but often rewarded as they enhances arowana's
color. Quarenteen is also recommanded as they might have eaten insecticide
contamination insects, eventhough the probabilty is small.
