This is my Hutch who I thought was a girl. (Actually thought was a boy cause I didn't buy him, but later figured it was a girl because I could see the ovipositor.) I'm not so sure anymore. After trying to introduce her/him into the sorority with the rest (at the same time I might add), she/he was a lot more aggressive than the others, and was the only one that got beat up a bit. Now I'm not so sure... So that's one question, what do you think?
Also, do I need to be treating with more than just Aquarium salt and extra conditioner (conditioner instructs to use extra when treating).
Right under his body, the fins seem to be almost transparent as I tried to show in the third picture.
