Hi,
I have a tang that has been in the aquarium for about 6 years.
Recently, I have noticed some white spots on his side - is it ich, something else, or just old age?

yes it is but happens with hippo tangs lots. path of the course keeping them. it comes and goes.
I had it happen to two of my Hippo's in two separate tanks at the same time of year this past spring. I put them both in hypo salinity for two months and I have seen mild signs of it yet again on one of the hippos this past week in one of my tanks. The other tank mates don't seem to be affected.
As previously stated...it seems to come a go, but I would keep a good eye on everyone else in the tank.
Good luck.
