i had 3 archers for a while, all might have been jaculatrix, but two were for certain and one could be chatareus. Anywho, as 3 fish they would occasionally come together, usually they would swim solo or double or the dominant would take turns on chasing one of the other guys. Not hyper aggressive toward each other but rarely school.
I added a 4th archer last week and it took about 3 days and then bam, all of the sudden they do not leave each others side. All four cruise the tank together. So for me at least, 4 was the magic number.
