This is a common bacterial infection that affects freshwater aquarium fish, particularly livebearing fish and catfish. It is not seen in marine fish, they can be infected by myxobacterial diseases that are similar to columnaris, yet this is very uncommon in the aquarium. Columnaris can enter the fish through the gills, mouth, or small wounds on the skin and results in an internal or external infection. It can have either a chronic progression of days or months or an acute progression with lesions spreading quickly, often wiping out whole populations of fish in just a few hours. It is highly contagious and may be spread through contaminated nets, specimen containers, and even food. This disease is brought on by stress, injury, inadequate diet, and poor water quality, including an unstable pH. To prevent Columnaris maintain your water with good biological filtration and weekly water changes that include vacuuming the substrate. Keep the tank well aerated, provide your fish with a varied diet, and don't overstock.
Ick is a disease that causes your fish to get small, grain-like spots on their body. Ick is also known as White Spot Disease or Ich. The fish may try to rub itself against the décor or the hard surfaces in the aquarium, giving an impression of scratching an itch. In freshwater, this disease is caused by protozoa named Ichthyophthirius Multifilis and is very contagious. The parasite spends a part of its life within the skin of the fish, where they form the white spots. These are the cysts. Once the cysts mature they fall down to the substrate and give rise to thousands of new free-swimming parasites that are free to prey upon other fish. An outbreak of Ick is very difficult to control if not noticed in the earlier stages. Since the parasite is released into the aquarium, the entire aquarium has to be treated. One of the effective ways to treat it is by adding salt to the water. The salt should be added gradually, slowly building upto5-8 tsp per gallon / 4L. Different fish have different tolerance level for salt. In the case of more sensitive fish, it is better to keep the level at 5 tsp. per gallon / 4L. Using medications based on Malachite green and formalin is also a way to control this parasite, but Malachite Green may be harmful to scaleless fish.
