With all of those fish, I'd bet the nitrates are off the chart...which is probably why he's jumpy.
As others have said, you need to think the herd quite a bit. In the meantime, do more water changes (say 25-50% a couple times per week).

unless you have something in there to specifically take out nitrates then the filters job is to turn ammonia-->nitrites-->nitrates and then you have to take out nitrates manually
