As their name implies, the 2-5 inch-long Pencilfish are quite slender. This unique shape, and their habit of quickly forming large schools and then dispersing (for reasons withheld from mere mortals!) allows enables to stand out in any aquarium. Pencilfish are quite hardy and often quick to breed, and do well in non-aggressive community aquariums. Several species, most only recently gaining attention, are available.
