Spotted hawkfish pair tank size

[mort]

Suggested sizes for the above please. I've seen different hawk pairs where they seem inseparable, so was wondering if you actually had to add that much more room for two. I'm guessing it may change depending on species and how much of a pair they actually are. Probably thinking of cirrhitichthys oxycephalus.

If they pr up they will be almost inseperable and can be fine in a 40g together. As a species, they are moderately aggressive in defending their perches.

Thanks, I've kept individuals and paired them for people but not had any real hands on experience.
