I purchased yesterday about 3 oclock a purple firefish, who seemed fine at the store. In my tank however he was swimming head down a lot, today he is hding a great deal (understandable) but also swimming head up, like a dolphin. I recall that my other firefish behaved funny the first few days too...however I am curious to know if this is some behaviour firefish exhibit or should I be worried?

As soon as the store opens at 12 I am calling them for advice.

Thank you, V2k
