Hi Wyatt,
I feed all of my newts with their very own, super special, dinner dish. That is, each tank has a small dish in the bottom of their tank (away from the filter system of course). Just put the food in the dish. They will smell the food, and in the beginning will be totally dumbfounded for awhile, but will eventually find their way to the dish and pig out.
It doesn't take too long, and they will know that the plate is a food drop-off. My more brilliant individuals actually wait in the dish and give me the look of, "Hey, when's dinner served? Now, I hope!."
I like to be creative with the dinner plates. Some are ashtrays (fired ceramic) that are shaped like leaves and shells. The colors are natural, and actually add a nice touch to the ambience of the tanks. My favorite places to find these items are GOODWILL, WAL-MART, DOLLAR STORE, they have really neat items, and are CHEAP.
Bottom line, the newts will train themselves!
