For the purpose of making illustrations of tiger barbs I would like to have a few of them in my aquarium. I read everywhere that a larger number should be kept. I currently have a shoal of 12 black ruby barbs.
What would happen when I add 2 or 3 tiger barbs to these? Are the black ruby's similar enough so that the tigers behave as if they live in a larger group of conspecifics? Of would the tigers eventually become nippy and start to damage the fins of the black ruby's?

Unfortunately this will not work, all but guaranteed. While these two fish may have similarities in pattern (the female Black Ruby does closely resemble the Tiger) they are two distinct species. Being shoaling species, they need a group of their own species. The profile here for the Tiger, Puntigrus tetrazona, explains this quite well. http://www.seriouslyfish.com/s.....razona/ A group of 8 at the very minimum, with more being much better, is necessary.
Having kept both species, I would not advise mixing them even in much larger quarters. The Black Ruby (Pethia nigrofasciata) http://www.seriouslyfish.com/s.....ciata/ is by barb standards a very peaceful fish, though very active (like all barbs), and should be separate from the Tiger.
