I had one many years ago when I was a kid. It was a real cool looking fish, my favorite at the time, but it basically hid all day then ate small fish at night. Tetras and Dainos disappeared and in turn his belly got huge ha ha. Its possible I wasn't ensuring it was getting enough food so this might not always happen. I'll prob keep another some day. Wish I had more to give ya, but thats all I really remember.
