Tiger Barbs are very hardy which makes them great for beginners and for cycling a new tank. I love Tigers and highly recommend, I have 6 tigers, 6 green tigers, 4 dwarf puffers and 2 plecos all in a 20 long tank. I have very successfully and easly breed them twice which their first offspring lives with 6 green painted tiger barbs, 6 glo lites, 6 neons, and a CAE. The last of their offspring lives in a 2.5 g until they get big enough to put in with others with becoming lunch. There are alot of different types you can get, tigers, green tigers, black tigers, black rubies, albinos, rosy, 6 banded and painted all of which have similar habits and should work well together. They are fin nippers and keeping them in a school of at least 6 should keep their nipping habits isolated to their own kind. Tetras are a good fish to keep with tiger barbs as well as, like I have dwarf puffers( my new favorite). Hope this helps and hope you enjoy.
