I've had this female Beta Fish for about a month now and it has started a very peculiar behavior the past few days and I'm worried it could be sick or something. She usually would rest on top of one of the plants in her fish bowl and isn't a very active fish, less active than other Betas I've seen. But the other day she suddenly started twisting, jerking, and spinning around, sort of like she was dancing. After a few seconds of this she slowly floats to the bottom of the bowl and lays down for hours, if I couldn't see her gills moving I'd think she had died. She has done this 3 times (that I've seen) in the past two days. Does anyone have an explanation for this behavior? I'm very worried. This link has a picture of her when she is laying on the rocks: http://www.facebook.com/photo.php?fbid=1738659705396&set=a.1154789829014.2024217.1205730030&type=1&theater CORRECTION: posted the wrong picture....
