Anchor Worm
Symptoms: Tiny white or green worms are attached to body or fin of fish, most likely on an open wound. Fish may scrap against objects in tank to get worms off. Contagious.

Treatment: Medicine - (Remove any activated carbon from filter - it may take medicine out of water)

Black spots (diplopstomiasis)
Small black speckles on body. Most common on piranha, silver dollar, and other fish of these types.

Treatment: Medicine - Black spot is fairly easy to cure. (Remove any activated carbon from filter - it may take medicine out of water)

 

Cataracts
Symptoms: White or grayish "foggy" substance covering eyes only. Cataracts are caused by fungus.

Treatment: Medicinemade to treat eye fungus. Eye Fungex by Aquatronics is a good choice. (Remove any activated carbon from filter - it may take medicine out of water)

Chilodonella (parasites)
Symptoms: Excess rubbing of skin, labored "breathing," loss of appetite, lethargy, cloudy skin, fish spending a lot of time dormant on aquarium floor. Chilodonella is a dangerous parasite because it has a wide temperature range that it can live in and also because symptoms don't show up until late in the disease when it may be to late to save the fish.

Treatment: Parasite medications - easily treat chilodonella. (Remove any activated carbon from filter - it may take medicine out of water)

Costia (parasites)
Symptoms: Symptoms for Costia are the same for all parasite infections - excess rubbing, thick mucus on body, lethargy, some redness on body. Costia is a common parasite that lives on fish normally and is usually kept in small populations by the fish's immune system. It only becomes a problem when the parasite population begins to grow large (such as with a fish that has a poor immune system).

Treatment: Parasite medication helps to treat costia. (Remove any activated carbon from filter - it may take medicine out of water)

Dropsy
Symptoms: Fish's abdomen is swollen and scales may stick out. Most common in gold fish. Dropsy is not a disease but a disorder caused by internal bacterial infections. It comes in 3 forms:

Acute Dropsy - Internal bacterial infection - see septicemia

Chronic Dropsy (cancer) - Internal organs become swollen. Fish must be isolated in early stage of disease.

Chronic Dropsy (parasites) - Swollen abdomen caused by parasites. Isolating fish prevents condition from infecting entire tank

Treatment : Maracyn-Two® will cure some forms of dropsy. Others require more complicated treatment that is very stressful on fish and not recommended unless under professional supervision. (Remove any activated carbon from filter - it may take medicine out of water)

Dermocystidium (uncommon)
Symptoms: This disease mainly affects Koi fish and is very uncommon. It causes raised pink/red swellings on the skin. Not much is known about it.

Treatment: There is no none treatments for dermocystidium. Contact vet for more information, as surgeries are available. Dermocystidium is not fatal, but additional diseases that can accompany it can be.

.

Epticemia-?????

 

Fin Rot (tail rot)
Symptoms: Fins (mainly tail) look jagged and torn and the "edges" are white. Fin rot is brought on by mainly stress but also injury poor eating habits and bad water conditions.

Treatment : If caught before disease reaches fin base, the fish will be able to regenerate the lost fin. Fin rot is easily cured with Maracyn® or Maracyn-Two® medicine (Remove any activated carbon from filter - it may take medicine out of water)

Fish Lice (argulus)
Symptoms: Fish frequently scrapes its body against gravel, rocks, or plants in effort to scrape off bothersome lice. You may see tiny white dots on fish's body. The "lice" are crustaceans which can swim from fish to fish, so affected fish should be isolated for treatment before the lice can spread.

Treatment: Lice is treated with medication, and it's wise to medicate the entire tank to kill lice eggs. (Remove any activated carbon from filter - it may take medicine out of water)

Fungus (body fungus,mouth fungus,tail fungus)
Symptoms: Fungus is usually a fuzzy gray or white substance. It grows in white tufts on the fish's lips, fins, and can cover the body in fuzzy gray/white patches.

Treatment: Fungus is easily treated with Maracyn® medication. (Remove any activated carbon from filter-it may take medicine out of water)

 

Gill Flukes
Symptoms: Gill area is red and inflamed and the inner part of the gill may protrude slightly. Fish may gasp at the waters surface and gills may move rapidly. Gill flukes are tiny parasites.

Treatment: They can be treated with Maracyn® or Maracyn-Two® medication. (Remove any activated carbon from filter - it may take medicine out of water)

Ich (white spot disease)
Symptoms: Small white spots appear on fish's body. Most noticeable on fins. This is probably one of the most common diseases in fish. Ich is caused by a protozoa, and generally breaks out among fish newly purchased from pet stores. Fish who are stressed are also more susceptible.

Treatment: Ich is easily treated with medication, and a number of medications are sold to treat it (such as Maracyn.) Ich can be fatal if not treated immediately. (Remove any activated carbon from filter - it may take medicine out of water)

Pop eye (cornybacteriosis)
Symptoms: Fish's eyes suddenly stick out more the normal because of hemorrhaging.
Its important to note that some fish have naturally protruding eyes, such as certain species of fancy goldfish. If bought as a juvenile, it will take up to 2 years to develop natural protruding eyes. Know how a fish should look as an adult before you accidentally treat it for non-existing diseases.

Treatment- Use Maracyn® or Maracyn-Two® medication (penicillin and tetracycline are available for treatment) Make sure you treat for septicemia (below) also, if fish is to survive.

Septicemia
Symptoms: Redness on body, blood streaks on skin and fins, inflamed blood vessels, hemorrhaging around the eyes, sluggishness and loss of appetite. Septicemia usually occurs along side other diseases, and can result from poor water conditions. There is a high risk of
Dropsy occurring as result of septicemia.

Treatment: Treat with Maracyn-Two medication. Isolate the fish. Then call a pet store or ask your vet for information on treatment. It is essential to treat septicemia immediately, or else it is fatal......

Scale Loss (stress)
Symptoms: Scales fall out, leaving pits on fish's hide. Scale loss is the result of extreme stress (probably caused by wrong water temperatures, bad PH and ammonia levels, frequent attacks from other fish, being new to the tank, trauma, overcrowding,lack of oxygen).

Treatment: "Stress Coat" can be bought in pet stores to help reduce stress, and also you should test water for PH and ammonia, and reduce overcrowding.

Skin Flukes
Symptoms: Fish rubs against things in attempt to rid itself of parasites living on the skin. Fins may become slightly frayed and skin may redden.

Treatment: Medication - (Remove any activated carbon from filter - it may take medicine out of water)

Slime Disease
Symptoms: Sluggishness, dull coloration (fish is mucus covered,) frayed fins, damaged gills and death. This disease causes the protective slime covering the fish's body to get thick and mucusy. Once disease spreads to gills, death will occur.

Treatment: Treat with store bought medications (Remove any activated carbon from filter - it may take medicine out of water)

Tuberculosis
WARNING-TB is transmittable to humans so exercise EXTREME caution when handling a TB infected fish! Symptoms: ulcers on the body ,fins clamped tight against body, faded colors and weight loss. Pop Eye can occur along side of TB.

Treatment: Quarantine fish as soon as symptoms shows to prevent other fish from getting sick. See a veterinarian for further instruction

Ulcers
Symptoms: An ulcer is basically a break in the skin which fails to heal. It looks like a circular (can be other shapes also) wound with white (dead tissue) around the edges. It may be inflamed and even expose muscle underneath. If left untreated the ulcer will grow larger. It's usually caused by bacteria. Ulcers are most common in ornamental pond fish, such as koi and goldfish

Treatment: Treatment can take weeks. One medication is called Genesyz, lymozyne Another is called melaflex. They also have "baths" use can use to treat fish for ulcers, but I don't recommend you try using bath's without consulting a vet or a pet store.

Velvet
Symptoms: Very small white speckles on fish. Resembles a fine powder. Velvet can be easily mistaken for Ich , but with velvet disease, the white speckles are smaller and finer and located mainly on body.

Treatment: Medicine (Remove any activated carbon from filter - it may take medicine out of water)

Wasting
Symptoms: Fish grows skinny and looks malnourished. Head may appear to large for the body.

Treatment: Wasting is caused by lack of eating. A fish may not eat if it is under stress, or not able to compete with other fish in the tank for food (overcrowding can cause this problem). If the fish is timid,smaller then its tank mates, not a fast swimmer (fancy goldfish,) or was recently ill, it will be unable to get its share of food. Put extra food into the tank so the fish in question can get its share, or you can even go as far as isolating the fish permanently (putting the fish in a separate tank just at meal times will cause stress). If fish is feeding normally and you rule out lack of food as the cause of wasting, it may be a symptom of TB. Read section on TB for more information and use EXTREME caution when dealing with TB.
