Hey guys! I'm currently stocking my 55 gallon and I have a few questions specifically about Angelfish. 1. The tank is in an area of the house where people will walk by it everyday and very frequently, at least every 30 minutes. Do Angel's scare easily? Would they not like this much activity in front of the tank? 2. I currently have a powerhead to provide current in the water for the schooling fish. I've heard that Angelfish don't like too much of a current. Should I remove it? It's at the bottom of the tank if that's relevant. 3. I'm planning on keeping 4 juveniles (just a bit bigger than the size of a U.S. quarter): will they have trouble finding food in such a big tank? And is 4 enough to cause at least one pair to form in the future? Thanks!
