I have my dogface with a huma trigger, marron clown, purple tang and green bird wrasse. All do well together. I also have a coral banded shrimp, pencil urchin, long spine urchin. Shrimp has been in about 1yr and the urchins about 2 months. I did have one of those large hermits but wrasse ate him in less then a week. Also have softies in this tank but its hit and miss when I add them. Puffer eats rics, shrooms, and zoas but dosen't touch other stuff.
