Hey guys. Just added a powder brown tang and hectors goby to the 90 gallon in which Jossmalo and I have joint custody of. We have a sixline wrasse that has been a model citizen throughout it's stay in the tank, but upon addition of the hectors goby he turned violent and has repeatedly attacked him. I thought for sure these two would get along fine. Should this pass or does the goby need to go back? Help!
