Whats wrong with my tang?

[maxheadroom]

He doesnt seem very active since I got him a week ago. He was very active at the LFS. I don't know what to do, please help! My params are:

salinity: 1.024
Temp: 78
Amonia: 0
Phos: 0
PH: 8.4
Nitrite:0
Nitrate:0

My 5 gallon tank has been up for 1 1/2 weeks and has a HOB filter, no skimmer yet. It also has a Koralia nano for flow. Any advice? I'll try to get a pic!

Tangs need to be kept in groups of at least 6 of the same species in order to do well in a large tank like 5 gallons.

The amount of fish to make up a Tang School is dependent on the species. Are they Percula Tangs or Leopard Tangs?

In my experiences, Red Sea Sailfins prefer Kosher salt...not sure if that's the case here.
