HELP...Damsel fish acting strange

[jords]

It's probably just dying. Fish who just die for the littlest reason will die like this. I would recommend QT'ing it if you can't be there for the whole process to watch it die. It's usually pretty quick if it is dying though if yours is dying. Eventually it'll just stop swimming and be pushed around by the current and may still be breathing, but I consider that the point of no return and absolute certainty.
