Thanks, I'm heading back to get another trifasciata, hopefully I'll actually get
a female this time! Today, one of the two were displaying, and he clearly had
a pointed anal fin. And I think the other would too, if he were displaying. That,
along with your info, tells me I've got two boys.

The trifasciatas have colored up some in the quarentine tank. Now the fins and
tail are showing color, basically red with a wide black border.
