Currently i container feed him in a one cup ziplock container, I have zebra danios which he refused (im not sure about the thiminase in these either). Ive tried worm chunks before but ive never gotten a reaction from that. I will try Snakeman's reptomin minnow plan and will try mixing as many guppies with some of my rosies. i think the reason why he didnt eat the danios is because he was stressed cause he shed the same day.
