Fish Disease

Fish disease is another common aquarium problem that most aquarists will have to address at some point.  Fortunately, there are precautions one can take to minimize the adverse effects of fish disease in the aquarium.

Fish Diseases and Fish Compatibility

The first thing one should keep in mind is that fish disease mostly will affect weakened or stressed fish.  This is why being mindful of Fish Compatibility is so very important.  If you place a passive fish with a tank full of more aggressive fish then it is highly likely to become susceptible to disease if it is not outright

killed.  The more aggressive fish will harass and badger the more passive fish and create great stress on it, greatly increasing the likelihood of it developing a disease.  Unfortunately, even when care is taken, fish that would normally be compatible can become victims of bullying by other fish in the tank.  If this becomes the case, then the merciful removal of the victimized fish before it infects others in the tank can be the best scenario.  However, if there is one fish that is doing the bullying then the removal of the most aggressive fish can restore balance to the tank.  When establishing an aquarium system this sort of scenario will inevitably play out before you develop a balanced community of fish in the aquarium.  With many species of fish, multiple females per male will make the males much happier and less aggressive.  Having multiple males per female will likely result in an overly aggressive tank susceptible to disease outbreaks among multiple fish.  Keep in mind that treating the individual fish and disease itself will be unlikely to be successful without a balance in the tank.  There are instances where the entire tank can become diseased as a result of an imbalance of the aggressiveness or an entire group of fish will become sick and die.  The role of fish aggressiveness and compatibility on fish disease can not be understated.

Fish Disease – Buying and Acclimating New Fish

There are a lot of other factors in fish disease however.  When you buy fish online or in a fish store, they have already taken a long trip to get there and this can create stress on the fish and make them more susceptible to fish disease.  Before you introduce any new fish to the aquarium look carefully for any signs of fish disease.  It is best to have a quarantine / hospital tank.  A 10-20 gallon tank with a small hang on back or internal filter will make a good quarantine / hospital tank for many systems.  If you have a larger tank with more expensive fish a 10g tank solely used as a hospital tank is a great investment.

It also comes with a net and an aquarium care guide that includes advice on how to set up and maintain your aquarium.

Any new fish can kept in the quarantine tank for the first few days to make sure no fish disease appears.  Even with a quarantine tank, disease can appear after being placed in the main tank due to stress caused by the other fish or improper acclimation.  Acclimation when introducing any fish to a new system is imperative.  To acclimate a fish one should place the bag with the new fish for 15 minutes to let the temperature adjust and let the existing fish become aware of the new tank mate.  Then punch or cut a small hole in the bag to let some of the water mix between the water in the bag and the tank.  If you do not want the water in the bag to get into the tank (due to possible contamination) then slowly add water from the tank to the bag and discard an equal amount of water from the bag.  The purpose of this is slowly bring the pH and water chemistry of the bag to the same levels as in the tank.  The total process should take between 30-45 minutes.  You need to make sure the bag has enough oxygen during this process.  Acclimation systems are available to assist with this process.

This is also a great solution to acclimating fish!

FA18X Aquarium Acclimation System fish disease
Prevent Fish Disease with the FA18X Aquarium Acclimation System

The FA18X aquarium acclimation system offers a simple and effective solution for the introduction of new aquatic life to your aquarium which will reduce stress on the fish and reduce the chance of fish disease. It combines the two best known acclimation techniques into a single package: Bag floating and dripping. The system is compatible to most aquariums and operates directly with the plastic bag containing the specimens to be introduced, which means no more messy buckets and dripping tubes; it comprises three separate parts: 1) The aquarium frame is engaged to the edge of the aquarium during acclimation, 2) the bag holder holds the plastic bag containing the specimens to be introduced, and 3) the dripping cup collects water from the aquarium to drip into the plastic bag at a controllable rate.

Adding water conditioner when introducing a new fish to a new environment will also help reduce the chance of fish disease developing.

Types of Fish Disease- Ich

A Clown Loach with Freshwater Ich Fish Disease
A Clown Loach with Freshwater Ich Fish Disease

By far the most common type of fish disease encountered is parasitic and is called Ich or Ick.  Ich is a protozoan disease that is often called ‘white spot disease.  It is caused by a microscopic protozoan parasite called ichthyophthiriasis in freshwater but a similar parasite called Cryptocaryon in saltwater causes saltwater Ich.  It can occur in both freshwater and saltwater species although it is due to different species parasites.  The symptoms are the same in freshwater and saltwater fish and treatment is similar.

A Tang with Saltwater Ich Fish Disease
A Tang with Saltwater Ich Fish Disease

The symptoms of ich are very evident and usually include characteristic white spots on the body and gills. In some infections, the ich organisms will only be found on the gills. As the disease progresses, the fish will become more irritated and may try to rub or scratch against the sides and bottom of the tank. The fish disease may then cause respiratory distress, severe agitation, loss of appetite, and eventually death.

Ich can spread to and infect an entire tank.  However, a healthy and well adjusted fish in a tank that otherwise has good water quality will usually have a fair amount of tolerance and ability to resist infections.  If you see an infected fish and remove it to a quarantine tank right away then chances are good that the infection will not take hold in the entire tank.  This is preferable as treating an entire tank will take 2-3 weeks and can disrupt the water chemistry in other ways.  It will require a lot of work and water changes to restore the tank back to normal.  If you can remove an infected fish within the first 24-48 hours then chances are that this can be avoided.  If you remove a fish then you will either need to eliminate it or quarantine the fish to a quarantine tank.  Once the infected fish is removed then we recommend the continuous use of a UV sterilizer, large water changes, and frequent addition of water conditioner for two weeks as a precaution.  Afterwards, if no further sign of infection is apparent then beneficial microfauna can be reintroduced to the tank.

Treatment of this fish disease includes formalin, malachite green, copper, or a combination of these. Methylene blue, and baths of potassium permanganate, quinine hydrochloride, and sodium chloride can also be used.  There are also some reef safe treatments available.  When using formalin, make sure to use recently purchased formalin. Formalin that is stored for long periods of time can convert to paraformaldehyde, which can be toxic to fish. An indicator that this has occurred is the formation of a white precipitate in the bottle. Malachite green and some other medications may also stain some decorations and silicone to a green color and may be toxic to piranhas, neons, sunfish, and some scaleless fish.  Use according as directed.  Lower temperatures and making the salinity different from the main tank can also help kill the parasite.  However, the fish will have to be carefully acclimated to prevent even further stress on the fish.  A quarantine tank with a combination of anti-ich medications and treatments will offer the best chance for a successful cure.  Even so, the fish is likely to succumb and only if the fish is completely cured and no symptoms are apparent for at least a week should re-introduction back to the tank be attempted.  Go to Fish Disease: Medications to find the right medicine for your fish.

If the infection spreads in the tank then the entire tank might need to be treated.  Some of these medications will kill invertebrates and beneficial microorganisms and bacteria in biological filters.  Some will also permanently stain some of the tubing in the system.  You will have to remove a denitrator filter from the system and let it circulate in a separate tank or bucket while this is done.  After 2-3 weeks you will need to use carbon and do water changes to remove the medication from the tank and gradually bring the system back to normal.  This can be time consuming and there is no guarantee that you will save most of the fish.  By far, the best way to deal with this is to not add any infected fish in the first place and if a fish becomes infected to remove it from the tank immediately and quarantine it before other fish become infected.

Types of Fish Disease- Other Diseases

There are countless other diseases that fish can get even though Ich is by far the most common.  Fish disease can be separated into 4 general types including bacterial infections, fungal infections, parasitic or protozoan infections, viral fish disease, and physical ailments and wounds.  Sometimes a symptom can be caused by more than one type of infection and the exact cause can not be determined.  This is true with the common fish diseases of Popeye and Dropsy (or fish bloating) which might be bacterial or viral in nature.  Go to Fish Disease: Medications to find the right medicine for any of these fish diseases.

The cost and trouble of treating a fish versus saying a little fish funeral prayer and flushing it is up to the aquarist.  If it’s a valuable fish that you are attached to then treatment makes sense.  If it’s a common and relatively inexpensive fish that you just got then frankly it might be better to move on.  If you have had it for years then you might be attached to it, but the fish disease is very likely due to old age and treatment will be unlikely to be successful.  It’s definitely best to use a quarantine tank if at all possible as treatment of the entire tank will often disrupt the biosystem and microfauna of the entire tank and this can in turn cause more stress to the fish and take a month or more to get back to normal after treatment.

Bacterial Fish Disease
Bacterial Fish Disease

Bacterial Diseases: Bacterial fish disease is usually characterized by red streaks or spots and/or swelling of the abdomen or eye. These are best treated by antibiotics such as penicillin, amoxicillin, or erythromycin.

 

 

Fungal Fish Disease
Fungal Fish Disease

Fungal Fish Disease: Common fungal infections often look like gray or white fluffy patches.  The fish may have erratic swimming, darting, scratching, or visible cotton-like tufts on skin, eyes, or mouth.  Anti-fungal medications are available that can even be safe to treat the entire tank with although a quarantine / hospital tank is nearly always preferable.

Fish Disease of unknown origin

Fish Disease of unknown origin.  It can be difficult to pinpoint whether a disease is bacterial or fungal in nature and multiple sources of disease can be present.  If this is the case a quarantine / hospital tank with multiple medications can be the best bet to successfully treat a fish.

 

Parasitic Fish Disease
Parasitic Fish Disease

Parasitic Fish Disease: There are a few other parasitic diseases other than Ich that fish can get.  Their treatment is the same as that for Ich.  They will often look slightly different from Ich in that instead of white spots, small wormlike flukes or flea looking creatures will be attached to the fish.

Viral Fish Disease
Viral Fish Disease

Viral Fish Disease:   Viral Fish Disease is hard to pinpoint and even harder to cure.  Variation in temperature may help.   Most medications used for control of fish disease are for other agents. Drugs are not effective against viral fish disease; however, antibiotics and other drugs may be used to control secondary bacterial infections. Management techniques that minimize stress and crowding, a quarantine tank, and temperature manipulation hold the greatest promise for control of viral fish disease.

fish disease
Physical Ailments

Physical Ailments: Physical Ailments are often the result of the environment. Poor quality water conditions can lead to fish gasping, not eating, jumping out of the tank, and more. Tank mate problems can result in nipped fins and bite wounds.  Quarantine might help heal the fish but if it’s put back in the tank with an aggressive fish that caused the problems then it will just happen all over again.

Fish Disease – Medications

  • Quickly kills ich parasite, typically within 24 hours of first dose
  • Use only in freshwater and saltwater aquariums not with reef aquariums

Rid your fish of ich fish disease quickly and effectively with API LIQUID SUPER ICK CURE Freshwater and Saltwater Fish Medication. API LIQUID SUPER ICK CURE Freshwater and Saltwater Fish Medication works quickly to heal freshwater fish of icthyophthirius (“Ich”) or Cryptocaryon, highly contagious parasitic fish disease. Ich, also called white spot fish disease, is a highly contagious and destructive, microscopic parasite that burrows into gill and skin tissue, causing severe damage and secondary infections. Early symptoms include white spots, darting and scratching against surfaces while more advanced stages can cause labored breathing. This freshwater fish treatment not only helps cure Ich, but it also provides a synthetic slime coat that helps protect against secondary infection, where the natural slime coating of the fish has been disturbed by the parasite. Use at the first sign of “Ich” or white spots. Some scaleless fish are sensitive to this medication, so treat them with 1/2 the normal dose. Some saltwater invertebrates, such as corals, may be sensitive to this product, so it is not recommended for reef aquariums. This medication will cause a slight discoloration of water which can be easily removed by adding activated carbon to the filter. Dose according to directions on product packaging and label. This treatment can be used in freshwater or saltwater aquariums.

Fish Disease – Water Quality and Diet

Many fish require higher water quality than others.  Some, such as freshwater Cichlids or saltwater Damsels, typically thrive in both aggressive environments and can tolerate relatively poor water quality.  Others such as freshwater Discus or Saltwater Butterfly fish require much higher water quality or will not do well in aggressive environments.  Other fish, notably saltwater Tangs, but also many species of other saltwater and freshwater fish will become diseased if they are not given a proper diet.  Tangs definitely require algae sheets to feed on regularly and many other fish will suffer and become ill if they do not receive a proper and varied diet.  This is why it is so important to do your research and due diligence when you purchase any fish.

Visit our Fish Food webpage to find the proper food for your fish so that you can avoid fish disease due to improper nutrition.

Water parameters can also play a part in fish disease.  Low oxygen or a sharp ammonia spike can actually kill fish.  A significant change in temperature or pH can also seriously harm or make fish more susceptible to various fish diseases.   Chronically high nitrates can cause kidney damage and reproductive problems in animals, including fish.
