I have always told people who buy new fish to quarentine for at least a month before adding new fish in with the old. I have had my new goldfish for 2 1/2 weeks now. I thought about adding him in with Depot, my current fish, for a while but decided I'd better not even though he had been healthy and exibited no signs of sickness. Today as I was cleaning his tank I noticed that he had a few anchor worms attached to him. I decide that he was not going to recover so I euthanized him with clove oil and threw out the fish net, quarentine tank, and the rocks and plant in the tank. I don't know how the worms deveoped. The quarentine tank had gone through several water changes and full cleanings since I got the fish. I'm just glad I didn't lose my other fish. Quarentining fish may seem like something that is unnecessary if the new fish look healthy but it is important if you don't want to lose a whole tankful.
