I have been in the hobby for six months. I have a 220 Gallon Mixed Reef Tank. Currently I have 1) Purple Tang 2) Blue Throat Trigger 3) Crosshatch Trigger 4) Convict Tang 5) Powder Tang 6) Diamond Goby 7) Three Clowns 8) Yellow Eye Tang 9) A bunch of snails, Clam, Spiny Sea Urchin 10) A Ribbon Eel who is new and will not eat :headwally: I would like to add the following 1) Six Line Wrasse 2) Foxface Rabbitfish 3) Harlequin Tusk 4) Blue Hippo Tang Will these fish be compatible. I know there is some risk with the crustaceans. The aggressive fish is the Blue Powder Tang. Last time I added fish it took two days of him attacking a mirror but then I took the mirror away and everyone got along.
