A huge range of fish hosts can be infected including the '''trout and salmon family, eels, goldfish, Siamese fighting fish, catfish and bass species'''. Cultured fish, free ranging fish and aquarium fish can all be affected although cultured fish reared in ponds or raceways are the primary concern.

Cultured fish, free ranging fish and aquarium fish can all be affected although cultured fish reared in ponds or raceways are the primary concern. It is not recognised as a problem in wild fish populations.
Columnaris disease can occur in cool and warm water fish, but is '''most prevalent in air temperatures above 12-14⁰C'''.

'''Potassium permanganate''' can be applied externally to adult fish and fry but can be toxic at high concentrations.
'''Potassium permanganate''', copper sulphate and hydrogen peroxide can be applied externally to adult fish and fry but can be toxic at high concentrations.
'''Terramycin''' can also be added to feed for adults, fry or broodstock, but resistance is emerging.
