Mine's going on a month now. Still eating most of what was listed above, although he does have an extreme preference for NLS. This, he'll eat every day. Currently, he more or less picks at everything else and does get his fill at feeding time, but shows no particular prejudicial preference for any one food other than the NLS pellets (1mm). He does DISLIKE some foods, tho, mainly Brine Srimp and Bloodworms, which is sadly probably what most people try first with finicky fish. He's not really "into" crustaceans as much as other fish, including herbivores like Rabbits and Tangs, can be. IOW, he seems to prefer to take other foods over Mysids and the like. Particle size continues to remain important, he doesn't touch anything that's much larger than a Ã"šÃ‚¼ grain of rice. He's taken some new foods as well, mainly SFBB Mussels. See my list of all foods used in prior pages.
HTH.
