I just checked the ph amonia nitrates and nitites and they all show to be good,,,the PH has always been a little low 7.8,,,the amonia was between 0ppm and .25ppm,,,the nitires was 0ppm,,,and the nitrates were 0ppm,,,,all means were taken a year ago to raise the ph I send alot of money trying to do this and it always just droped right back down to 7.8,,,All fish seemed to be fine all this time,,,but I did add a blue tang from my lfs and it died with in three days,,,over Christmas,,, but it had no sign of infection,,,it seemd to die of shock,,,no one told me about acclimateing anthing,,,but this blue tang did act crazy and stupid just like this clown is doing now,,,I hope this is more info to help solve this problem,,,,thanks for all the help so far,,,,more is needed,,,thanks again,,,,oh and the gills look fine and he does have labored breathing at times,,,he almost acts like he is blind,,,,no sighns of eyes looking unhealthy,,,when I feed he really goes crazy running into things,,,like he can smell the food but he cant see it to eat it to eat it,,,,should take him out and try to feed him manually???And how???
