disease in fish- life cycle Ichtyophtirius multifilis

Ichtyophtirius multifilis is one type of protozoa that often cause disease in fish, both ornamental fish and fish consumption. Protozoa are small in size, so can not be seen with the naked eye. In the body of the fish that attacked this protozoan will form white spots 0.5 to 1 mm in diameter so that the disease is often called white spot. This white spot is actually a colony of tens to hundreds Ichtyophtirius multifilis

Ichtyophtirius multifilis damaging fish mucus cells, and can cause bleeding. After 8 days of life in fish, these parasites are mature enough to establish a breeding. These parasites escape from the body of fish, and floating in the water for some time. Then attach themselves to an object, like the plants form a layer of skin that looks as mucus. Form so-called cyste. This parasite in cyste divide within 5 hours (depending on temperature), forming thousands of small multifilis Ichtyophtirius. If within 48 jm not find ditempelinya fish, then the children of this parasite will die, the children of this parasite attached to the mucous membrane of the fish.

life cycle Ichtyophtirius multifilis can be divided into four phases:
a. parasitic phase: When living in the fish
b. Phase pre-cyste: Having grown up and break away from the fish's body, but has not yet established cyste.
c. Cyste Phase: During the splitting process occurs, wrapped wall mucus, and attached to an object in water.
d. Phase post-cyste: Represent the seeds of parasites coming out of cyste.

White Spot and Velvet Disease - the treatment ...

These two diseases are rare in Discus due to the high water temperature (30°C) they are kept at. But if you do happen to get these parasites then heat treatment will cure it without drugs. White spot is treated with 34°C for 10 days, whereas Velvet Disease is treated for 2 days. Heat treatment can cure many problems, because most parasites can’t withstand high temperatures. Another parasite, which is also treated with heat, is Costia: 33°C - 34°C for 4 days.

 When heat treatment is used, use a separate low wattage externally adjustable heater and keep a careful eye on the temperature as often as possible. Make adjustments only if someone is home for a few hours after the adjustment, to minimise the risk of "cooking" your fish. When administering medications, calculate the tank capacity accurately to avoid overdosing. A good method is to take the internal dimensions in centimeters and multiply the length by width by height to the water line divided by 1000.

Usually if velvet, fish color body be dark / black, fin fin his contract, likes to rub her body into a nearby object and usually get together in a corner / own.  procedure of fish disease treatment 

1. Discus quarantine suspected of velvet 2. Enter Acriflavine chloramphenicol 1.5 grams + 20 ml + 1-2 salt fish into a tank containing approximately 100 liters for quarantine. 3. Replace the aerator is rather large. 4. Install the heater 30 C.  5. If the water is turbid and white in the day after tomorrow, chiffon. Add a solution of the same as before. Do so until the disc looks healthy (usually 1 week).   6. eat less (fasting).
