A great addition to any community aquarium, They do prefer to school and they look their best when they are in schools.
When they stop swimming, they will flick their caudal fin like a pair of scissors hence the name.
I haven't found them to be aggressive toward long fin species like other Rasboras.
Well worth buying.
