Exlain,show a picture anything about what your tank is why this particular fish is in there reef safe or not, how big, what type. So basically anything. I am looking for some inspiration as too what I should add as my show fish in my reef tank 180gallon. I right now have a clown tang who I love. I want to add a trigger and a harlequin tusk as the big three showfish. I had a puffer as a showfish but he died due to the fact he did not eat after awhile and he succumed to it. still to this day I can not figure it out. He was doing so well always out and not being picked on or picking on anybody.
