well I have 3 Percula Clown. About 4 days ago the smallest one just started acting weird. Sits in one spot on the bottom of the tank? doesnt move practically all day. eats very little. Now another one is starting to do the same. There color seems to be normal, maybe just a little not as bright as orange as the ok one, but no white spots or anything, just acting weird. Could they be sick?? anyone seen anything like this or any ideas.. I also have 3 Damsels and they all act fine,
