Default Common Fish Disease (Picture included)

Ich / Ick
Symptoms -
White spots that look very similar to grains of salt or white sand on the skin.
Scratching against objects (skin irritation)
Clamped fins, may "hang" and gasp near surface if infection reaches the gills.
Treatment
Raise the temperature to around upper 70F to 80F, there is also a lot of medication available at LFS. Giving fish a salt bath is also helpful.
Pictures


Fin / Tail Rot
Symptoms
Ragged or split fins, frequently white around the edges. Fin and tail rot can arise from importation, rough handling, fighting, and fin nipping overcrowding, poor nutrition, and bad water conditions can also contribute.
Treatments -
Frequent water change; make sure your tank is cycled. Test for ammonia, nitrites, nitrates.

Body Fungus
Symptoms
White, brown, or gray cotton-like growths on the fins or skin of brackish and freshwater fish
Treatments
Medication available at LFS
Pictures


Mouth Fungus
Symptoms
Hazy-white marks can be seen on the body, fins, and mouth of the fish at the onset of the disease. Cotton- or wool-like tufts appear in the mouth area, and most fish lose their appetite and appear quite thin.
Treatments
Medication available at LFS
Pictures


Columnaris
Symptoms -
The mouth "fungus" is commonly called cotton-mouth because the fish's mouth seems to be covered with a thread-like cottonish substance. Since the initial leisions look somewhat like cotton, columnaris is often confused with true fungus. Note that when examined very closely, fungus has distinct hair-like filaments which shoot out, whereas columnaris is more like fuzz or lint.

Columnaris usually affects the mouth area but can also appear as yellowish-brown, white, or grayish-white spots on some part of the head, fins, gills, or body which are usually surrounded by a reddish area. This type commonly takes what is known as a saddleback pattern on the fish's body.
Treatments
Malachite green (except for fry), salt or antibiotics as last resort

Pictures


Dropsy
Symptoms
The fish's body will become swelled with fluid it is unable to expel. Eventually the swelling will cause the scales to raise, giving the fish what is called the "pine-cone" appearance.

Accute Dropsy: Sudden swelling: A bacterial infection will cause internal bleeding.
Chronic Dropsy: Slow swelling: Growing tumors, or even parasites, in the fish may cause it to swell.
Chronic Dropsy: Slow swelling: Mycobacterium tuberculosis. Highly contagious!
Other unknown causes, such as a virus, or permanent damage to the fish's internal organs. Damage to kidneys can occur due to over-use of medication or use of too strong of medication.
Treatments
It is usually fatal and not curable. However, if infection is due to bacteria, try salt bath, anti-biotic
Pictures


Velvet
Symptoms
Scratches against hard objects
Fish is lethargic
Loss of appetite and weight loss
Rapid, labored breathing
Fins clamped against body
Fine yellow or rusty colored film on skin
In advanced stages skin peeks off
Treatment
Raise water temperature to upper 70F to 80F, dim lights for several days, add aquarium salt, treat with copper sulphate for ten days
Discontinue carbon filtration during treatment
Aquarium Pharmaceuticals General Cure, Jungle Velvet Guard, also, many of the same cures for ich and other parasitic diseases will work.

Hole-In-The-Head (HITH)
Symptoms
Small pits or holes develop in the sensory regions of the head and body, especially along the lateral line. Sometimes have trouble swimming due to lose balance
Treatment
There is varies of medication from LFS. Feeding a varied, nutritious diet can contribute to healing and positively affect overall fish health.
Check http://www.worldcichlids.com/diseases/Adamhith.html for more info.

Neon Tetra Disease (NTD)
Symptoms
Heavily infected fish lose color (esp. the red stripe in Neon Tetras), have curvature of the spine, fin rot, and emaciation. Tetras seem especially susceptible to this infection, although other fishes can be affected as well.
Treatments
No known, dependable cure at this moment.
Pictures


Pop Eye
Symptoms
Fish eye pops out, lose vision
Treatments
Medications from LFS, frequent water change; make sure your tank is cycled. Test for ammonia, nitrites, nitrates. Also add aquarium salt, 1 teaspoon / 5 gallons would help.
Pictures


Cloudy Eye
Symptoms
Fish eyes look white or grayish, cloudy. It will cause blindness
Treatments
Frequent water change; make sure your tank is cycled. Test for ammonia, nitrites, nitrates. Wait a week or two before using anti-biotic medication.

Fish Tuberculosis (TB) HARMFUL TO HUMAN!!
Symptoms
Loss of appetite, pale and emaciated appearance. Clamped fin, refuse to eat, hiding behavior.
Treatments
There is no known treatment, maybe strong anti-biotic.
Pictures


Swim Bladder Disease
Symptoms
The fish whirl or wobble around the aquarium.
Fish will sometimes float upside down, or show some bloat. This disease usually has no physical sign.
Treatments
Different depending on species; goldfish are very susceptible and sometimes cured by discontinuation of diet and salt bath, followed by change in diet to high fiber digestible foods. However, other fish may require antibiotics and have a worse prognosis. Recently introduced fish that exhibited signs within a matter of minutes have the worst prognosis of all, and there is often no cure for trauma to the swim bladder.
Picture


Enteric Red Mouth
Symptoms
Dark color
Hemorrhages at base of paired fins and vent
Reddening of corners of mouth, gums, palate and tongue (hence the name of the disease)
Reddening of gill cover
Hemorrhaging in eyes
Treatments
No known treatment
Pictures


Lymphocystis (Cauliflower Disease)
Symptoms
Cauliflower like growths on the skin and fins. It usually starts as a few small white cysts, which grow over time.
Treatments
No known effect treatments. Do water changes frequently to reduce ammonia and nitrites will help fish battle this disease.

Fish Tumors -
Symptoms
You can see tumors grow on the body
Treatments
No known treatment for most tumors
Pictures


Anchor Worm
Symptoms
These parasites are elongated with two egg sacs at the posterior end. They usually embed themselves with hook-like anchors in the body wall of the fish, and a raised ulcer can develop where it attaches.
Treatments
Can be physically removed or treat with formula from LFS
Pictures


Fish Louse
Symptoms
It is a disk shape parasite with legs, hard to notice.
Treatments
Maybe physically removed, formula from LFS should also help. Fish louse is usually seen on the fish that are kept outdoor.
Pictures


Flukes (Gill, Eye or Skin)
Symptoms
Rapid breathing, loss of appetite, discolored gill filaments, and swollen gills. Infected fish may also gasp at the water surface or lay at the bottom
Treatments
Outbreaks of gill flukes can be treated with copper- or formalin-based remedies. Great care should be taken, as these treatments can be very harmful to invertebrates and even some fish.

Hope all those didn't come from your tanks. Just wanted to mention for all the koi folks out there, that koi herpes is getting to be really bad as well. Be careful where you get your fish, and as with all fish, quarantine first. It is easier to prevent a disease than cure it.
