Freshwater Fish Disease Symptoms and Treatment
Here you will identify some of the more frequent freshwater fish ailments along with their symptoms and treatment. This Freshwater fish disease list where we list the common name, symptoms and treatment options for your sick freshwater fish. Before you dose any medication on your aquarium make certain that you have properly diagnosed the freshwater fish ailment and try to figure out why your fish have the disease or problem to start. Many diseases are brought on by the fish being stressed due to transport or water quality issues. If you’ve just set up your tank, please read about new tank syndrome. See the “Nitrogen Cycle” and proper acclamation process.It’s a very good idea to have a small quarantine tank for new fish so that you may monitor the fish for a few weeks before adding the fish to your main tank. You can also use the quarantine tank for your fish that come down with a freshwater fish disease and can avoid adding chemicals to your main tank. Always practice good fish acclimation techniques and don’t rush things.

Try to determine the underlying problem before medicating. Often times there are water quality issues that need to be remedied first. Get and use an aquarium test kit and take the appropriate measures to correct the water in your aquarium.
Whenever you use any type of medication on your tropical fish, first remove any carbon in your filtration system. If left in, the carbon will remove the medication from the water, doing you no good. Read the directions on the medication bottle very carefully!
To sum up, first determine the cause of the freshwater fish disease, fix any obvious problem(s) (water quality problems and/or tank mates), figure out which disease your fish has by closely observing the symptoms and then treat if necessary.
Ammonia poisoning is easily preventable. Avoid adding expensive and less hardy tropical fish until the aquarium has cycled. For more information on cycling your aquarium please read about the aquarium nitrogen cycle. You can use a substance called zeolite to help absorb ammonia but the best solution is to ensure that your aquarium has cycled and that your tank is not overcrowded. If your tank has not yet completed the nitrogen cycle, you will need to perform frequent water changes to keep the ammonia levels down.
This is not really a disease, but a symptom of a bacterial infection and possibly malnutrition. There are medications available but try to increase the quality of the water by performing a 25% water change every other day and increase the quality of fish food given. If your fish’s condition doesn’t improve, try the medication. Your local pet store should have medication for this disease. Remove any carbon filtration before using medication because the carbon will remove the medication from the water.
This is a fairly common fish disease and your local pet store should have medication you can use. Ich usually arises due to poor water quality. You can increase the temperature of your water to 82 degrees Fahrenheit to speed up the cycle time of this parasite. Remove any carbon filtration before using medication because the carbon will absorb the medication. Easily preventable by using a quarantine tank for a few weeks before introducing new arrivals into your main tank.
Rotting fins, loss of appetite and laying on the bottom of the tank. This is due to a bacteria that infects the fins of the fish. It is sometimes brought about by bullying from other fish and fin nipping. Most often it is due to poor water quality.
There are medications available such as Tetracycline from Mardel Labs. Remove any carbon filtration before using medication because the carbon will absorb the medication. Before using medication though try increasing the quality of the foods you are feeding your fish, separate them from any fin nippers and step up your water change schedule.

There are many theories out there, but no conclusive scientific evidence as to what exactly causes this disease. However, it may be attributed to poor water quality, lack of proper nutrition and/or the use of activated carbon for prolonged periods. However, there have been no scientific studies about the effects of the prolonged use activate carbon causing hole in the head, it’s just speculation. Be sure to give your fish the best water that you can by performing frequent water changes. Give them vitamin enriched foods and change out or stop using activated carbon.
Nitrite / Nitrate poisoning is not a disease but will kill your tropical fish if not remedied. It results from having a large bio-load on the filtration system or from not performing enough water changes. Perform a partial water change immediately and monitor the nitrite and nitrate levels closely until the situation is resolved. You may have too many fish in the tank and will need to perform more frequent water changes. Nitrite readings on your aquarium water test kit would indicate that your tank is still in the aquarium nitrogen cycle nitrite phase, or it is undergoing a mini-cycle if you’ve recently added more fish to the tank.
Check the temperature of the water. Higher water temperatures require higher levels of oxygen. You will need to increase the aeration in the tank with airstones and/or powerheads and increase the flow rate with your filters. Try to decrease the temperature of the water by floating ice cubes in plastic baggies and turning off the tank light. If sun light is entering the tank from a nearby window, try closing the shades. Also, if you have an overcrowded aquarium you will definitely need to increase the aeration in your tank.
This is usually the result of a bacterial infection. Try to give your fish the best water possible by performing frequent water changes. To treat this problem you can use a treatment such as Tetracycline from Mardel Labs. If possible, increase the quality of food given. Supplement with vitamin enriched foods.
