One has to distinguish between the norm and the minority. Sometimes an individual fish can behave outside the norm for the species; we don't know why, scientifically--except in cases where the environment (tank space, water parameters, aquascape, tankmates) is different from what the fish requires naturally and erratic behaviours result. But the wise aquarist always assumes the "norm" for a species. Those of us who have not done this in the past usually live to regret it. Dealing with a fish that one has had for several months and that overnight becomes a terror is not always easy. Don't risk your other fish. I stand by the advice in the profile.
