I think good water quality is what gets the best results, not saying you have poor water. For food currently in feeding mostly NLS and also some New Era pellets. They eat the NLS but it looks like I'm making them eat broccoli (not that I don't like broccoli, but you get the point). I know they are very high quality but honestly I want to find something that they love as much as my old bleekeri loved the New Era pellets...
