I have several different colonies of Hydnophora. I placed them all around my GBTA. After a few exploratory "skirmishes", the anemone keeps it's distance from two of the colonies, but it stings (and causes some recession) in the third colony.
The three colonies are distinctly different. They are all different shades of green. In fact, the smallest colony is the most "flourescent" and that is the one the GBTA avoids most.
