How do they determine how much space a fish needs? I know with freshwater you can do the 1 inch of adult size per 1 gallon as a general guideline but you can't do that with saltwater.
I'm asking because my lfs has several beautiful types of fairy wrasse in but they all seem to need 50 gallon tanks but only get 3-3.5 inches. Is this all a behavior thing? Are these requirements still needed if it would be the only fish in the tank? Thanks.
