I have had up to 13 chromis that always schooled. They moved in unison like it was an Olympic event. Now the remaining 9 (little suckers jump!) don't school in the same way. Sort of a loose unorganized formation if at all. The change happened right after I gave away my large monodactylis argentus. My guess is that they don't feel as threatened.
