anyway, I tracked it down. the instagram accnt is a reposter so that did not help, but I tracked it to a tweet repost that had the actual orig accnts name:

Too many girlfriends? Not a problem for the hawkfish! The species in this family are protogynous, meaning that all individuals start out as females at birth. As adults, they form harems around a dominant male; but if there are too many females, then one or more of them will change into males and branch off with up to half of the remaining females. Not enough girlfriends? Not a problem either! If the number of females in a harem gets too low, or if they lose a challenge from another male, the former harem leader will simply revert back to being female.

No shirt, no bra, completely bare torso, just like cis men are allowed to

It's about desexualizing breasts and "female presenting nipples" and not being criminalized for our bodies if we want to go topless because it's a million damn degrees out. This was a popular growing movement that was still widely known a decade ago!
