yup NLS is a High Quality pellets...thats what i used to get my umbee the great green, blue and purple to red colors on mines...=] loving it...and so is he...lol
I picked some up but they were hella expensive (11 bucks for 5.8oz) It took a while before my fish would even eat them, but I cut everything else out of their diet and fed em a few pellets everyday until they got hungry enough to eat em. Once they started though they love em now, all my fish have great color.
