I have a noticed A change in activity, there is more aggression in the tank; bottom feeding for the first time is causing territory issues.
The Color is so slightly different, if its even different at all; hard to say could be placebo effect. Over all I am happy with the food, as Most seems to like it, although they all liked Hikari. I will try a mix of floating and sinking NLS to see if it will decrees aggression, IF I can get a good deal I can see using it over hikari just for the dietary content. However its hard to beat Hikari prices, and while I am sure my fish can look better; I won't say they look bad from the exclusive Hikari diet.
