OK.. I love the Hikari.. it has really brought the color out in my zebra obliques. Hoping that the NLS will be even better..? I offer alot of different thinks to my little guys... Ive tried lettuce/raw spinach, but they were not impressed.. seemed to like boiled peas/green beans though... as well as raw shrimp, brine shrimp, zuchini, and bloodworms... they even enjoy the algea wafers...
