Do Tiger Barb fish attack Kissing Fish?

  we have tiger barbs and kissing fish in the same tank and our kissing fish's tail looks nibbled on.
Tiger barbs are known to be fin nippers, especially if they are not kept in a large school, or the tank is too small. Kissing gourami can will grow into a large (8-12 ") and quite aggressive fish itself, so a big tank is going to be needed anyway.

They could! They are supposed to be ok together but that's exactly what we had. We had 2 tiger barbs and 2 kissing gouramis and now we only have one kissing fish! He does NOT like other fish, we even got another kind of fish afterwards so he wouldn't be lonely and the next day only half of it was there!!! So yes some fish will attack others.
Yes, they will attack your kissing fish. Tigerbarb will bite other fish fin , they are dominent species ...
Tiger barbs are very aggressive when not kept in schools. When you have a group of 6 or more, the aggression stays mostly among themselves.
tiger barbs are notorious fin nippers.
