for color id suggest dainichi ultima. my old zhen zhu loved it, and the pink/red came in really nice.
bio-gold is a great staple food and is highly suggested, however for color, its nott he best option
i tried alot of dainichi products. the only one that has asthaxithin is "color fx" and that is the only type that my lfs doesn't carry. it is great food that accents blues and other colors well. the red enhancing seemed weak to me though. i do want to try the colorfx as soon as i can get it.
