That question is going to open a can of worms ....
That being said, I suggest pellets, but it can be very difficult to get them on pellets .... tilapia filets, and some other fish filets people have had a lot of success using .... I haven't gotten an Armatus over 2 feet so can't say what I'm feeding is correct, but pellets are always great from what I've seen and heard .... I had 2 die on me at the 11 inch mark, and I think it was linked to feeding them too much smelt .... silversides can be used to wean off live, however feeding them all the time can possibly lead to the same smelt related deaths .... the one I have now is about 15 inches and has eaten pellets since he was 3-4 inches and is doing great, won't even look at other food
