It has been a very long time since my bettas saw another of their own kind. I propped a small mirror against side of the aquarium to let the fish see himself. They are still feisty fellows! Pinkie showing his colors:
I think this is the first time I've seen Oliver display. He has more red color in his dorsal fin than I realized (the red showing under opened gill covers looks alarming, but is normal.
This photo shows his form nicely, but disappointed there's bad reflection of my own hand in the glass
And I like this one backlit which shows the shape of his finnage against light
I finally got a photo of the two new black kuhlis together- one hanging out in the rotala stems!
