Wow that must be quite expensive. I have NLS, hikari, and Ken's food. I've had the NLS for over a year and have barely used it. IDK just not quite happy with it for some reason compared to the hikari. I will have to use it once I run out of the hikari. Out of hikari I have used micropellets, algae wafers, and the cory wafers. Usually only buy hikari when I am given a giftcard for petsmart, then I make them price match it. I am phasing over to the Ken's food. Super cheap and never had a problem with it. Bought like 1.5 pounds, 3 different kinds for $20 shipped a while back. I freeze a lot of my dry foods because I have at least a 2 year supply . The food from ken's comes in 1/2 bags. I fill small containers with the food as I need it. The rest all stays frozen. When looking for a good food it should contain astaxanthin and/or garlic. NLS small fish formula has a high amount of garlic. Its suppose to increase appetite, but doesn't seem to work with my fish lol. However both these ingredients are what make up most of the cost of the high quality fish foods. NLS though is just too expensive, dry fish food shouldn't cost that much IMO.i did use it but find NLS from the US is better, healthier and cheaper . Buy in bulk few times a year.
