So far I've given him bloodworm cube (which my angelfish ate most of), baby brine cube (again, angelfish), a couple peas (which he tried to eat one and then spit it out ... haha), part of a worm as shown on the video, and a couple more sinking wafers. Right now he is swimming up and down the corner of the tank. I do have a couple cory cats in the tank and they are much faster than him, and I think one is missing.
I was curious if I could give him fresh caught native fish filets (bass, crappie, sunfish), boneless of course, cut into pieces? I am unsure if there is risk of disease, so could I freeze or boil to kill off the bacteria and then feed?
