How big of a tank do you have?
How many tigers were you planning on getting?
From my own experience with them, the first you listed should be fine so long as your tank is large enough to house at least 6 tiger barbs.
I have 15 tiger barbs, and they seems to be doing okay with my angelfishes and other danios...as danios could outswim barbs easy and i have lots of plants and driftwood hiding spaces to break the tention from one and other..and I notice sometimes small barb will try to nip fin bigger, and vice versa, but seetms like they are being playful..and havent had a single barb died withitin last 2 months or so..good luck with yours!
