I have a Tiger Barb that keeps circling endlessly. I bellieve I had this problem in the past and it was a parasite I don't remember what I used to remedy the problem. Please let me know and thanks in advance I love this site!

I'm not an expert on fish parasites but I think there are a number of them that could cause fish to swim eractically and in circles. I'm not sure which your fish has. You might treat with a general parasite killing medication. Ick/ich causes fish to scratch themselves, and fish don't always have the white spots if it's not that bad. When it's bad, they can swim in circles but you'd see spots all over them. It might be some sort of fluke that your fish has as they are pretty common.
