For the past few days my male festae has been extremely dark in coloration. He also seems to be swimming extremely sluggish and purpousless back and forth, banging into one side of the tank softly then back to the other side. Seems less interested in food also but is still eating what ever his female doesnt snap up. Heres a pic of his color vs usual coloration. Any ideas guys??
