I HAVE ABOUT 8 FISH IN MY TANK AND THEY ARE ALL SHOWING SIGNS OF STRESS
AND DON'T LOOK GOOD. IT ALL STARTED WHEN MY CLOWN GOBIE'S SKIN STARTED
TO GET SPOTS OF DISCOLORATION ON HIM, EVENTUALLY THAT CLEARED UP AND
OUT OF KNOW WHERE MY FIRE FISH DIES. THEN MY SIX LINE WRASSE AND
SAILFIN TANG START TO ACT WEIRD BY BREATHING REAL HARD AND THE WRASSE
WEDGES HIMSELF INTO THE ROCKS AND STAYS THEIR ALL DAY LOOKING LIKE HE
IS GOING TO DIE. THE FISH WONT EAT, EXCEPT 2 OR 3 WHICH SEEM FINE. ALL
OF MY LEVAL'S ARE PERFECT nitrite 0 nitrate 10ppm ph 8.2 ammonia 20ppm,
salinity 1.024 temp 80 i have doubled the carbon in the tank and
did a extra 10 gal change for the week. what could be the problem and
how to fix it? this is a 55 gal tank and the fish have been like this
for a while. also i noticed the clown gobie has disapeared. help please!

does it look like they have little white patches??? they might have ich I would set up a hospital tank and treat all the fish in that tank and keep them in there for about eight weeks if is ich you have to act fast.

their is nothing on the fish's bodies at all.

I would keep an eye on them. if they start to get white patches I would quarantine them. you might want to turn your light cycle down by a couple of hours also this will releive some stress.
