HELP!!!!!! Added too much fresh water to my tank, fish look bad..

[derrick80f]

While performing routine tank maintenance earlier, I accidentally added too much fresh water to my 150g tank apparently, because 2 fish look bad. The salinity is perfect now, but I'm worried because my dogface puffer and foxface are just sitting still looking bad.. they are moving and all I know they are alive but I'm worried. Will they recover?

How much did the salinity drop and how quickly? Also, how fast did you bring it back up?

 

[griss]

Large fast fluctuations are not good. Slow/gradual not so bad, but still not good

I have used marine fish tank salt to raise salinity -- BUT as griss says, it must be done slowly.

If it was a sudden drop in salinity, and the pH hadn't changed, then the fish should be okay. Consider that some marine fish treatments are a freshwater dip or even a longer (30 min) freshwater bath with proper pH, which many marine fish can handle.

How did this pan out fella ?
