@ Harlequin Mania many thanks for your expert advise. I'm not a beginner but I have never had a Potter Angel before and I don't buy a species before I'm 100% sure that I have all basis covered. People must be humble and ask their more experienced Reefer Friends for advise I have a Hawaiian Flame Back ,Coral Beauty, 2 Tangs and 2 pairs each of designer Clown Fish in a 5.5 x 2.5 x2.5 FOWLR Tank. That will be my last addition as they must be able to roam freely
Many thanks again
Warmest Aloha
