Rams are almost always bottom fish, or at least the lower half of the tank.
They may investigate all over, but they usually make the center of their territory a flat rock in the bottom of the tank.
Any fish with sort of puffed out gills may have a problem.
When this fish also spends time at the top of the tank I know there is a problem. Most especially when it is a species that is normally found lower in the tank.
Any fish might gulp air or water rich in oxygen at the surface of the tank, or can learn there is food up there, so come up to eat. (I have seem more than one Pleco swimming up side down to catch flakes off the surface).
Look into the various parasites that can infest the gills. Ich is one of them. Have you added any new fish to this tank recently? There are other parasites that are slower to attack. Several fish diseases can affect the gills. Read up about Flavobacteria columnare. Usually makes its appearance as a grey or white patch on the fish, but can also attack the gills.
Her age could be a problem. I understand these are not long lived fish.
