Post your water readings. Did this fish just start acting this way suddenly? How good is your water circulation?

 

[fish are good]

PH:0.8ppm
Nitrite:0ppm
Ammonia:0-.25ppm
Nitrate:0ppm
Salinity:it was really low-1.020 so i raised it and it is fairly good now
Good curculation

Has something recently died in the tank or why do you have ammonia in there? Also could you re-post your pH, it should be between 8.2 and 8.4. Also what is the temp in the tank? How long have you had the Sailfin?

A sudden drop in the SG and then quickly raising it back up will cause a fair amount of stress to your fish. How are you raising it? What are you using to measure the SG?
