I really think you should watch him...
I'm definitely still keeping a very close eye on the situation. If she does turn out to be a he, I'll just have to get another divider and make room in one of the 10 gallons for him. Or find another home, which I really don't want to do.
For now at least, s/he peacefully gets along with everyone else.
