Purple tang in hypo too long

[BrianBell1974]

I have had my purple tang @ 1.008 to 1.009 since 02/05/06 due to an ich issue.
He seemed to be doing well until today.
The water parameters appear fine. and I use a refractometer to track the salinity.
Today he has been swimming spiratically upside down and into the glass then just lays on his side and pants.
He is in a 29 gallon he may just be getting stressed in such a small tank. He is a tiny tang a little bigger than a quarter.

The main tank has been fallow since 02/05/06. Can I drip acclimate him back to the tank or will going to 1.025 after a couple hours acclimation kill him?
I have to do something because I am sure he will die quickly he is extremely stressed all of a sudden.

Thanks for the help

Steven Pro, in his article on marine ich, comments that moving the salinity up too quickly can cause problems. He target 0.001-0.002 units per day:

I have never needed hyposalinity, so I can't help more. Good luck!

When you raise the salinity level it should be done for a 3-7 day period, the tank should be plenty big for that little guy. Do you have hiding place in there to help reduce stress?

I have some PVC pipe in there. He seems to have calmed down.
I will keep an I on him tonight.

Have you also been keeping an eye on your pH level? My yellow tang started behaving odd during hypo and I realized I had not managed the pH level. As soon as I corrected the problem the tang settled down.
