can i add 2 more fish to y tank

Question
i have a 55 gallon tank with one medium sized clown, small clown... angel blenty... purple tang... can i put a angel flame fish and a blue tang in the tank... i have a reef tank with 80 lbs of coral and live rock... live sand... anemones .... invertebrates... 50 blue leg and 20 turbo snales... emerald crabs and 2 banded coral and 2 fire and one cleaner shrimp... 3 year old established tank...

Answer
Hi Billy:  I would not mix other tangs or similarly shaped fish with a purple tang... they can be very aggressive towards their own kind.  In fact one purple tang per tank is good.  The flame angel may work... but that too would be iffy because they are similarly shaped to some tangs.  dave
