Type of disesase: Acidosis is not a disease. It is actually a water quality issue.
Causes: Low pH levels (below 5.5)
Symptoms: Excess mucous, inflammation of the skin, and erosion of the gills. Affected fish dart about the tank and will often jump out of the water. Respiration increases, and the fish may be observed at the surface of the water gasping for air.
Type of disesase: Chlorine intoxication is not a disease. It is actually a water quality issue.
Causes: From chlorine contained in tapwater.
Symptoms: Flashing. Gasping. Rapid breathing. Red gills. Pale body colour. Body may appear rough and irritated. Fish usually die with gills wide open...
Type of disesase: Excess Carbon Dioxide is not a disease. It is actually a breathing issue.
Causes: When one adds CO2 to the tank for plant fertilization, there is a risk of oversaturating the water. A tank overstalked with fish or with dirty filter material will also be a risk.
Symptoms: The fish gasp at the water surface for air, as if they are suffocating.
Type of disesase: This is not a disease. It is actually a posoning caused by Hydrogen Sulfide
Causes: Caused by anaerobic (without air) decay of debris and waste in the gravel, sump, filter or in the tank. Detritus builds up in dead spots can cause pockets of dangerous levels of hydrogen sulfide. A sand bed eventually developed sizable anaerobic pockets.
Symptoms: Gasping, darkened gills, increased respiration rate, shimmy. Rotten egg smell in the aquarium or sump.
Type of disesase: Nitrogen intoxication is not a disease. It is actually a water quality issue.
Causes: Overcrowed tank, insufficient maintenance, insufficient filtration, over feeding.
Symptoms: Rapid breathing, usually at the surface of the water. Shimmy. Quick darting movements at first, followed by lethargy as the fish begin to die. Fish coloration appears either normal or more intense until after death. Gills may turn red or bloody.
