My angel tetra fish is too cool to school

A while back bought a bunch of angel tetra, and one does not hang out with the school of them really at all, in fact he seems to avoid it, even getting a little aggressive when he can not get his space. Does this mean he is too cool to school (like in the song but for fish instead of people)? :D

Not sure if this counts as shower "observations"/puns as stated in the rule as it does not explain what it means by that. Sorry if this is somehow against those rules.
