i was wondering if datnoids and other monster fish like ATF, Pirahna and the like... can they be taught to eat pellets? i've been reading some threads and some says that "New Life Spectrum pellet" and "Omega One" will enhance the color of fishes. I would really love to have some really monster fish but i want them to learn to eat pellets and shrimps not feeders (because they carrry all sorts of diseases). and make them semi-agressive since i don't want to clean the tank and end up in the ER with my finger gone.
