most schooling fish will get nippy because they are stressed. This is usually because the school isn't large enough
They are great, little bold personalities but often brought back to the lfs cause they show different behavioir than other tetras. The constantly show of and "communicate" that way. They can chase a female till it is exahausted in a hiding place.
Recent studies have proven beyond doubt that when shoaling fish are maintained in too small a group (one study used five as the absolute minimum) aggression is almost certain to occur. Normally-aggressive species heighten their aggressive tendencies, while normally peaceful species can become nippy and more like bullies not only to their own but other species as well. Think of this as the fish's means of responding to what it finds intolerable; it simply "lashes out" out of frustration. Sometimes it may respond the opposite--by withdrawing so much that it simply wastes away.
