Here is a video of my Polypterus delhezi eating worms. He's only a juvenile about 5 inches long, but he's really cool and has a big appetite. Right now, he's in a 29 gallon tank by himself because he ate all his guppy friends ! Does anyone have any ideas for tank mates that won't hurt him. I don't want anything to happen to him. Here is a great video of him in his tank. I look forward to hearing your suggestions.
