I've had a feather fin Syno for a while now - He's been slightly lethargic these past few days and swimming at the surface. Oxygen seems to be fine. The main symptom seems to be shaking/twitching of his fins (mainly the pectoral fins) it doesn’t seem to effect his swimming - but its as if he has tremors.... has anyone seen this before, and can anyone suggest a treatment?

I have seen that in other species, and often it is a sign of stress.

Have you tested the water?
Ammonia, nitrite, nitrate.
GH, KH, pH.
These fish are quite tolerant of a wide range of pH, KH and GH, but sudden changes can be irritating to them.

A water change may help, even if the tests seem to show nothing wrong. There may be some disease or parasite getting started, or some other issue going on.
