Also i have noticed the stimulants dont really have an effect with these guys. I have tried. It seems to be a texture thing. They are definately hungry and hit the food hard, but spit it out after a sample. They try but refuse. These are picky fish. Spoil them with what they like, and once they are settled, mix in foods really close to what they are eating already....baby steps. Their live food to pellet is too drastic, and they usually would rather starve
