Bath treatment (fishkeeping)

Bath treatments are disease treatments that originated since the earliest days of goldfish culture. They are easy to carry out. One of the most effective procedure is called the salt bath which is quite effective in eradicating ciliated parasites from the fish. However, there are also useless, thus not recommended, bath treatments such as the use of certain antibiotics or vitamins in the bath.

Bath treatment can either be short-term (a "dip") or long-term (from a few hours to 12 or 24 hours or longer).^[1]
