CHILL chill chill chill totally normal, mine do it too. add some floating plants for him to frolic in, or some better caves to hide in on the bottom.
 
In future, a better symptomatic description than "at the top behind a filter" will be needed. Provide a pic, if possible, plus water parameters from test results, temp, filtration, physiological observations, etc. We all want to help. But, we'll need something tangible to base the help on. Sometimes the 'fish diagnosis' crystal ball has to go out for calibration.

Using a tank divider for the time being would probably be the easiest route, although I don't know what your current setup looks like.
 
I would just find a way to divide the senegal for the time being. What some people do is find an appropriately sized rubbermaid container that fits within the frame of the tank, drill holes in it so water can flow through and have a sort of "hospital" area in there. I don't know what a larger tank would do in this instance. Maybe you can separate until you put some size on the senegal...or possibly put a few more hiding spots in the tank.
