Awesome thread and some great info on these great fish! I love my Ctenopoma. He's one of my favorite fish. I know this thread is a little old but thought I would share this video of my Cteno hunting ghost shrimp. This video was taken in 2009 when he was about a year old. I've had him about 6 or 7 years now. Hopefully this link will work. I'm new to the MFK community and still learning my way around.
