Seachem Metroplex contains Metronidazole and that is used for treating internal protozoan infections in fish.
Seachem focus is an antibiotic, This might damage filter bacteria but I'm not sure so monitor the ammonia and nitrite levels and if you start to get readings above 0ppm, then it does.
Neither of those 2 medications will treat intestinal worms so you will need to find Flubendazole if the fish has worms.

Is the ram really skinny in the belly area?
The picture makes it look sunken in. If that is the case, how long has it been sunken in around the belly?
