I personally think Hikari is a great brand. Its cheap, comes in bulk, carnivores love it, and really does enhance colors in most fish especially the red color. BUT if we are talking about pure color enhancing, NLS wins hands down. Some of my datnoids take hikari and some take NLS, the NLS has given my one datnoid that takes strictly NLS a beautiful gold base. Not to mention NLS has so much great ingredients in it compared to Hikari. Don't get me wrong Hikari is great, but if money wasn't an issue and all my fish would take NLS I would strictly use NLS.
