I have the Philippine Regal in my 65 gal at the office. He is the star of the tank there. My home tank I already have a Red Sea and a Pacific Regal. I don't know if I should add a third. The dominate Regal in my home tank is the Red Sea. If it was the other way around, I would add a third. As it is I am not sure. What is your advise? Size wise the Red Sea is largest, and the Philippine is the smallest but not by much, about 1/2 inch shorter.
In person, the color diferent between my Red Sea and Pacific is very striking. Mainly the Yellow bars are much wider in the Red Sea which give a much brighter "yellow" fish in compair to the Pacific.
Your Bali above is still very small. Still have his false eye and hardly have any spike.
