Disese Type: Bacterial (gram negative rods)
Organism: Flexibacter columnaris
Names: Columnaris, Cotton-Wool, Cotton-Mouth, Flexibacter, Mouth Fungus
Descrption: Often mistaken for a fungal infection because of its mold-like lesions, Columnaris is a common bacterial infection in cultured fish, particularly livebearing fish and catfish. Its name is derived from columnar shaped bacteria, which are present in virtually all aquarium environments.
Symptoms:
White spots on mouth, edges of scales, and fins
Cottony growth that eats away at the mouth
Fins disintegrate beginning at the edges
'Saddleback' lesion near the dorsal fin
Fungus often invades the affected skin
Rapid gilling in cases where gills are infected
Treatment:
Change water
Vacuum gravel
Add aquarium salt
Treat with copper sulfate or antibiotic
Discontinue carbon filtration during treatment
Prevetion:
Quarantine new fish for two weeks
Maintain high water quality
Provide fish with a nutritionally balanced diet
Medicate fish prophylactically before moving them
Disinfect nets and other equipment before using them with hydrogen peroxide
