Well, Randy, I'm guessing that you have just set this tank up since you mentioned, "New Tank Syndrome".

What that ususually refers to is the build up of ammonia because the biological filter is not yet working. In order to compensate for that I'd recommend that you reduce feeding for a few days and do a 20% water change. If you have an ammonia test kit, it might be helpful to test the water before you do a water change.

Be sure you properly treat the new water to remove chlorine and make sure the temperature of the new water and the tank match.

Good Luck!
