Aquarium Round Swimming

Fish lice

Symptoms: Rational behavior you see the fish trying to scratch against anything it can find. You will also see transparent round shaped parasites fish close to the body. It can be red or marked areas where the parasite before.

Reason: These parasites, which have eight legs, are lice (Argulus) that is attached by suction cups, break the skin and feed on fish. The eggs are deposited outside the fish. Some say it is often confused with algae, but if you look hard enough you'll see what they are if they are adults, as are green, but young are not so obvious.

Treatment: adult parasites can be removed by the forceps once the fish has been removed from the aquarium. Treat the area affected with an antiseptic. You can then use a treatment tank can meet the young and newborn parasites with an organophosphate as Dimlin (diflubenzuron), but such chemical is banned in many countries.

I noticed that Parazin P, an appropriate medicine for the treatment of infestations of crustaceans has been proposed and takes several weeks to take effect, which is based on the life cycle of the parasite.

I have also read treatment by which the fish is rubbed with a piece of paper towel roll on the affected area parasite, the fish is immersed in water (at the same temperature of the main tank) and all the parasites in the field leaves the fish! Apparently, the parasites do not like dry conditions, hence the use of dry paper roll. You can not make any damage, why not try?

Fungus

Symptoms: The body areas that are affected are those in which has been the mucus layer that protects the damaged skin. You will see cotton as material attached to the fish or the appearance of all skin may appear dirty. You can see what your disease is also called the cotton. "types of fungi are typically Saprolegnia, Achlya, Leptomitus and Pythium.

Exposure Reason: This is a secondary infection as often occurs after an initial injury has happened or when a parasite has been active or after the fish has suffered from the white spot. It could also be due to poor water quality.

Treatment: You can use a fungicide owners and phenoxyethanol to treat individual fish in a hospital / quarantine tank, but trying to determine the cause of the outbreak and establish corrective action in place, otherwise it may break out again. Salt baths are another alternative or the use of topical gentian violet on the affected area.

Gill trematodes (Dactylogyrus)

Symptoms: You see the fish rub against objects to relieve the itching. It may be breathing fast or gulping for oxygen at the surface. As the disease takes hold of the fish will become lethargic and try to isolate themselves in a corner or stay on the bottom of the tank. It will turn off their food, have swollen gills and gill nets may be kept open or closed.

Reason: A parasitic worm as up to 2 mm long infesting the gills of fish and played there. It has hooks on your body to dig into the meat, causing damage and possible bacterial infection. But the main effect is to reduce the ability of fish to breathe and obtain enough oxygen, leading eventually to death.

Treatment: This is an infectious disease so treatment of all fish is recommended. As the eggs are very resistant parasites, repeated treatments for a couple of weeks will be necessary to kill the worms newborns. Fluke tabs are no longer recommended.

Praziquantel (Droncit (U.S.) or Drontal (United Kingdom) are preferred because they are safer for fish. Other treatments include Paragon United Kingdom (for mild infections and safe with shrimp and snails or Sterazin (for serious infections, but it is not safe with shrimp and snails. A follow-up treatment is bacterial probably suitable to counter any secondary infection caused by the parasite.

Hole in the head (Hexamitiasis)

Symptoms: As the disease can affect both the intestines and the skin underneath can see white stringy feces literally holes in the poor fish's head. Disc fish are particularly susceptible. You can see fish swimming backwards, its color may darken and can hide his head down.

Reason: A parasite called Hexamita is the culprit. He lives in the intestine and can become a problem when fish are stressed and / or weak because to poor environmental conditions.

Treatment: Metronidazole at about 500 mg per 10 gallons is the usual dose. Dissolve the drug in hot water first. There are several treatments may be needed more than two weeks with 50 percent water changes carried out before each treatment. He noted that some popular add malachite green to work in secondary infections.

As the disease is also internal medicated fish food is also appropriate. 250 mg (0.25g) metronidazole in 25 g of food make it possible.
