Ornamental Fish 11.jpg


A pair of adult gold severums were purchased by a hobbyist for use as broodstock. They were placed in a 38-L aquarium equipped with a sponge filter and air stone. Water temperature was adjusted to 26°C (78.8°F). Seven days after arrival, the fish were lethargic and the owner noticed they were completely covered with white dots. He phoned the individual who had sold him the fish, a trusted friend, and was assured that the fish had never been sick during the 18 months they had been in his care. He had purchased them as juveniles from a reputable pet store and never had to question their health.
