I have a 75 gallon tank running since last May. Building up a mixed reef, LPS and SPS. Current stock is 3 Firefish, 3 Bangai Cardinals, small Scopus Tang and a Yellow Candy Hogfish. What can be another active occupant. Was looking at Flasher Wrasses but seems they don't work with the Hogfish. Or are the Flashers okay just not other wrasses?
