Jan aquas are the craziest imh- uranus ruled and all that. I should know, lol. I see-saw between being social and anti-social. The greatest adventures i ever had were by myself, no doubt. I have no rules when alone
I think each sun aquarius is unique and defined by their moon. The moon tends to shape the aqua. I have seen talkative, chirpy and vivacious aquas in both January and February. My brother is a January aqua. He is pretty social and outgoing when it comes to his friends. However, he doesn't really become the life of the party and socialize with acquaintances openly. My brother's moon is Pisces, which really mellows his aqua out. I'm sun and moon aqua. I can be very social and make friends with all the strangers in the room or I can be one hell of a loner. It all depends on my mood.
Not so sure about the jan/feb deal. Think Aquas are very social around people we respect/like/want to get to know. May appear as loners in our own world otherwise.
In my opinion, Jan ones are more social and Feb ones are more loners.
