I have 3 of them, and was wondering if the pygmy kind do not school? They all seem to just find a spot and chill out when they aren't exploring by themselves.

Well, pygmies tend to prefer larger schools than their fullsized counterparts. 10 or more is ideal, 5-6 is more common. Also, schooling fish that do not school are happy fish, usually. The schooling instinct is a result of feeling the need to be "protected." When they do not feel threatened, they stop schooling and get the guts to go exploring on their own.
But yes, they are schooling fish. I suspect you don't have enough of them and would suggest picking up three more - as you know, they're tiny, don't take up much space, and don't use up much bio-space.
