I got a marine betta two or three weeks ago. It is starting to come out and be more social with other fish and today I saw it hunting when I put some live salt water feeder fish in the tank.

If you have never seen a marine betta hunt it is definitely a spectacle to see. It curls its tail to be parallel to its head using the false eye to confuse the prey, then "snap" it lunges towards the pray... kind of successfully.

If I had a video camera I would record it and put a clip up.
