your ram (Bolivian butterfly cichlid) is a bit sunken in around the head and looks like it has a couple of whitespots on its dorsal (top) fin. But that could be just the angle and light.
If the fish are twitching several times a minute there is something irritating them.
Costia and its relatives aren't very big and often only show up as a slight discolouration on the body. They can live in warm or cold water tanks. But the pictures don't show any signs of it so its possibly something else.
The ulcer and sores on the gourami are typical signs of TB but if the fish's immune system is run down then that would also allow things like that to develop.
