Treating and Curing Arowana Diseases
Arowanas when housed in your aquariums enhances the overall appearance of your living room. Its rich red, green, and silver hues are striking to one’s eye and can be easily captive-bred. Like all fish species arowanas are also vulnerable to a host of diseases when their immune system is down.
Set up your arowana fish tank well in advance. Once purchased and brought home, float the fish containing bag in the tank for about 30 min to equalize the temperature levels. Open the bag, introduce some tank water into it then release your fish into the tank after 15 min or so. If it appears stressed out do not feed him immediately, instead give him some time to get adjusted to its new environment.
A very common problem that most arowana owners face is loss of appetite in their pet fish. They settle themselves at the bottom of the tank with no or minimum food intake. The possible causes vary from change in environment, poor water conditions, frequent and large water change, or even overfeeding. In juvenile arowanas stomach ailments can occur when fed repeatedly with rotten food or given unshelled fish feeds. When this stomach disorder occurs, stop feeding your pet for a couple of days and calm it down by covering the back and sides of the tank. Once it appears relaxed, begin feeding it with centipedes as this is something that arowanas cannot resist and gradually an improvement should be noted.
Foul water conditions within the tank caused by food left to rot and improper removal of fish poop; high levels of ammonia, nitrogen dioxide, and nitrate in water reducing oxygen levels make it an ideal breeding ground for bacteria and parasites. Parasites both external and internal can affect arowanas. When your pet gets infected the gills are the first part to be affected. The gills become a perfect place for parasites to hide in and suck out all nutrients from the fish. Increase the tank temperature to inhibit them from multiplying, add 0.8 g quinine to every 1 liter of tank water, and increase the oxygen levels.
Similarly fish lice or anchor worms affecting your arowana causes reddened areas to develop on your pet. Your pet arowana may rub frequently against the aquarium walls to minimize irritation losing its luster in the process. The best mode of treatment would be to add 1 g metronidazole for every 100 liters of tank water, soak your pet fish in concentrated salt solution, and sterilize the tank interiors thoroughly.
Again improper maintenance of the fish tank with limited space for movement at times lead to the gill covers curling upwards exposing it, causing breathing difficulties and making it essential for your fish to constantly push its head above water surface for gulps of air. If left untreated, this can cause death in arowanas. When the first signs of breathing difficulties are noted, an immediate water change of 20%-30% should be carried out. Refresh 20% of tank water every alternate day. If symptoms continue, call in a vet for further medical assistance to prevent gill rotting which is highly contagious and difficult to control.
Cloudy eyes can also occur when the water conditions are not maintained adequately. It eventually causes the eye to swell, and if left unchecked can lead to permanent blindness. At early stages of this disease development add coarse salt, change 1/3 of tank water, and increase the temperatures within. Observe your pet for a couple of days and if improvement is noted, change water every third day with more aquarium salt added. Medications may be required in severe cases to bathe your fish in. Seek the help of a vet if such a need arises to revive your pet fish’s health back.
Constantly feeding food that sinks to the bottom of the tank for your arowana can cause droopy eye in them. They are surface eaters and not designed to look downwards for food. Moreover bright decorative objects installed at the bottom of your tank grab their attention and looking down continually at them lead to this development. When ‘lazy’ eye syndrome is noted in your pet fish, shift to feeding him with dry pellets for a couple of days. Killing live feeds enable them to float on water surface making it easy for your arowana to fetch. However, once this eye abnormality arises treatment is limited. Preventing it from occurring is recommended and if established it becomes more of a cosmetic concern, your pet will not die from this abnormality.
Frail fins and fin rot also strike arowanas. Keep the water really clean then add aquarium salt and tetracycline at required quantities. If this does not bring the desired results refresh the tank water totally and start Maracyn dosing along with aquarium salt.
Broken barbels and dropped scale can occur in arowanas when injuries are caused from its own force with incessant darting around or violent behavior. These however regenerate themselves over time with proper tank maintenance and diet.
Prevention is better than cure, thus water quality should be maintained constantly. Remove fish poop daily with the help of a fish net, refresh tank water only with aged tap water, and install proper water filters. Constant observation for abnormalities and immediate treatment offered if any are noted will ensure that your pet arowana is healthy and happy.
