I have a love for tangs.
I have a 150 gallon reef with a kole tang, yellow tang, sailfin tang, blue hippo tang, and a powder blue tang.

They do on occasion get into each others way and start sword fighting with their barbs but this is only once in a full moon. 99% of the time they are great with each other. However keep in mind just because 1 person has a good experience doesn't mean it will be good for you. Always use caution when introducing new tank mates.
