I agree, but they also clamp their fins when they do not like the water.

The fins come out when they're divided. They posture across the divider all the time. I'll see if I can get some photos with the fins up. Yours actually has more impressive fins than mine.

Beautiful fish! Are they a pair?

Definitely not so far. Divider was out for a couple hours tonight and is back in now.
