[reefman420]

i have had a koran angel in my tank for about a month now.i recently added a sailfin tang to the group.the first thing the koran did was swim by him then left ,came back and started chaseing him.then took a few bites out of his dorsil fin.i dont get it.he dont bother the damsel the six lined wrasse,the serpent star the snails or any of the hermits..the tang just sits in the upper right hand corner of my tank.i bought this fish on the hopeing to see its beautifull harmoney within my community.please if u have any suggestions on how to get them to be acwaint please let me now asap

He probably didn't bother any fish that were in the tank before him (it was their territory) but now it's his and he isn't having any intruders. Try lights off and rearrange the rock work. See what happens the next day after the lights come back on.

i tried rearanging the rock,what about takeing him out for a day or something

Your 55g tank is too small for these two fish to live peacefully. Get a bigger tank, or take one of them back to the LFS. The tang will never be happy in a 55g.. Sailfins get over 15"!

You failed to mention in this thread that your tank was only 55 gallons. In fairness to the fish, I would try to find new homes for both fish. Your tank isn't large enough for either one.
